https://en.wikipedia.org/wiki/Verlinde%20algebra | In mathematics, a Verlinde algebra is a finite-dimensional associative algebra introduced by , with a basis of elements φλ corresponding to primary fields of a rational two-dimensional conformal field theory, whose structure constants N describe fusion of primary fields.
Verlinde formula
In terms of the modular S-matrix, the fusion coefficients are given by
where is the component-wise complex conjugate of .
Twisted equivariant K-theory
If G is a compact Lie group, there is a rational conformal field theory whose primary fields correspond to the representations λ of some fixed level of loop group of G. For this special case showed that the Verlinde algebra can be identified with twisted equivariant K-theory of G.

https://en.wikipedia.org/wiki/Myers%E2%80%93Steenrod%20theorem | Two theorems in the mathematical field of Riemannian geometry bear the name Myers–Steenrod theorem, both from a 1939 paper by Myers and Steenrod. The first states that every distance-preserving map (that is, an isometry of metric spaces) between two connected Riemannian manifolds is a smooth isometry of Riemannian manifolds. A simpler proof was subsequently given by Richard Palais in 1957. The main difficulty lies in showing that a distance-preserving map, which is a priori only continuous, is actually differentiable.
The second theorem, which is much more difficult to prove, states that the isometry group of a Riemannian manifold is a Lie group. For instance, the group of isometries of the two-dimensional unit sphere is the orthogonal group O(3).

https://en.wikipedia.org/wiki/Preissmann%27s%20theorem | In Riemannian geometry, a field of mathematics, Preissmann's theorem is a statement that restricts the possible topology of a negatively curved compact Riemannian manifold. It is named for Alexandre Preissmann, who published a proof in 1943.
Preissmann's theorem
Consider a closed manifold with a Riemannian metric of negative sectional curvature. Preissmann's theorem states that every non-trivial abelian subgroup of the fundamental group must be isomorphic to the additive group of integers, . This can loosely be interpreted as saying that the fundamental group of such a manifold must be highly nonabelian. Moreover, the fundamental group itself cannot be abelian.
As an example, Preissmann's theorem implies that the -dimensional torus admits no Riemannian metric of strictly negative sectional curvature (unless is two). More generally, the product of two closed manifolds of positive dimensions does not admit a Riemannian metric of strictly negative sectional curvature.
The standard proof of Preissmann's theorem deals with the constraints that negative curvature makes on the lengths and angles of geodesics. However, it may also be proved by techniques of partial differential equations, as a direct corollary of James Eells and Joseph Sampson's foundational theorem on harmonic maps.
Flat torus theorem
The Preissmann theorem may be viewed as a special case of the more powerful flat torus theorem obtained by Detlef Gromoll and Joseph Wolf, and independently by Blaine Lawson and Shing-Tung Yau. This establishes that, under nonpositivity of the sectional curvature, abelian subgroups of the fundamental group are represented by geometrically special submanifolds: totally geodesic isometric immersions of a flat torus.
There is a well-developed theory of Alexandrov spaces which extends the theory of upper bounds on sectional curvature to the context of metric spaces. The flat torus theorem, along with the special case of the Preissmann theorem, can be put into this broader context.

https://en.wikipedia.org/wiki/Eastern%20Orthodoxy%20in%20Azerbaijan | Eastern Orthodoxy in Azerbaijan is the main Christian and the second largest religious group in the Republic of Azerbaijan (after Islam). According to statistics, the Eastern Orthodox, or Byzantine tradition in Azerbaijan is 2.3% (209.7 thousand people). The territory of Azerbaijan is in the jurisdiction of the Baku-Azerbaijan Diocese of the Russian Orthodox Church.
History of Eastern Orthodoxy in Azerbaijan
Serious changes in the Caucasian Albanian church occurred under the Arab rule, when the Catholicos Nerses I Bakur (688-704) attempted to convert to Chalcedonism, thus recognizing the spiritual authority of Constantinople. He was deposed by the Grand Duke of Albania Shero and other feudal lords who remained faithful to the Albanian church, and cursed at the national church cathedral. In the second half of the 10th century, the population of the left-bank Albania (Hereti) was included in the sphere of influence of the decision of the Chalcedon Council of the Georgian Church, adopted in the 7th century and got a great impact of Georgia.
When the territories of Transcaucasia entered the Russian Empire, jurisdiction of Georgian Exarchate was expanded, encompassing territories of modern-day Georgia, Armenia and Azerbaijan. In 1905, Eparchy of Baku, nowadays Baku and Caspian Eparchy, was established. The Albanian Catholicos of the church in 1813 by the decree of Tsar Nicholas I passed into the status of the metropolite of the Albanian church.
Eastern Orthodoxy became wide spread in Azerbaijan at the beginning of the 19th century.
Eastern Orthodoxy in Azerbaijan nowadays
In 1815, the first Russian Orthodox church appeared in Baku. Later such churches were built in Ganja, Goranboy (Borisi-Russian village, 1842), Shemakha (Alty-Aghadj village, 1834), Lankaran (Vel village, 1838), and Gedabek (Slavyanka village, 1844).
There were 21 sectarian villages in Baku during 1868.
In 1905, the Baku Diocese of the Russian Orthodox Church was established. During the Soviet era, the authorities repressed the priests of the Baku diocese, but in 1944 two churches were opened.
In 1998, the Baku-Caspian Diocese of the Russian Orthodox Church was established. On March 22, 2011, the decision of the Holy Synod of the Russian Orthodox Church was changed to the Baku-Caspian diocese in Baku-Azerbaijan.
In 2011 there were six Eastern Orthodox churches in the country. Five of them belong to the Russian Orthodox church (ROC): three of them are located in Baku one in Ganja and one in Khachmaz.
Another temple belongs to the jurisdiction of the Georgian Orthodox Church - the Church of St. George in the village of Gakh-Inguila in the Qakh district, where the Ingiloy Georgians live compactly (about 7,500 people).
In 2013, November, President Ilham Aliyev participated in the opening ceremony of Orthodox Religious and Cultural Center of Baku and Azerbaijan Eparchy. Firstly, The President visited the Holy Myrrhbearers Cathedral.

https://en.wikipedia.org/wiki/Geospatial%20topology | Geospatial topology is the study and application of qualitative spatial relationships between geographic features, or between representations of such features in geographic information, such as in geographic information systems (GIS). For example, the fact that two regions overlap or that one contains the other are examples of topological relationships. It is thus the application of the mathematics of topology to GIS, and is distinct from, but complementary to the many aspects of geographic information that are based on quantitative spatial measurements through coordinate geometry. Topology appears in many aspects of geographic information science and GIS practice, including the discovery of inherent relationships through spatial query, vector overlay and map algebra; the enforcement of expected relationships as validation rules stored in geospatial data; and the use of stored topological relationships in applications such as network analysis.
Spatial topology is the generalization of geospatial topology for non-geographic domains, e.g., CAD software.
Topological relationships
In keeping with the definition of topology, a topological relationship between two geographic phenomena is any spatial relation that is not sensitive to measurable aspects of space, including transformations of space (e.g. map projection). Thus, it includes most qualitative spatial relations, such as two features being "adjacent," "overlapping," "disjoint," or one being "within" another; conversely, one feature being "5km from" another, or one feature being "due north of" another are metric relations. One of the first developments of Geographic Information Science in the early 1990s was the work of Max Egenhofer, Eliseo Clementini, Peter di Felice, and others to develop a concise theory of such relations commonly called the 9-Intersection Model, which characterizes the range of topological relationships based on the relationships between the interiors, exteriors, and boundaries of features.
These relationships can also be classified semantically:
Inherent relationships are those that are important to the existence or identity of one or both of the related phenomena, such as one expressed in a boundary definition or being a manifestation of a mereological relationship. For example, Nebraska lies within the United States simply because the former was created by the latter as a partition of the territory of the latter. The Missouri River is adjacent to the state of Nebraska because the definition of the boundary of the state says so. These relationships are often stored and enforced in topologically-savvy data.
Coincidental relationships are those that are not crucial to the existence of either, although they can be very important. For example, the fact that the Platte River passes through Nebraska is coincidental because both would still exist unproblematically if the relationship did not exist. These relationships are rarely stored as such, but are usually discovered an |
https://en.wikipedia.org/wiki/Veblen%27s%20theorem | In mathematics, Veblen's theorem, introduced by , states that the set of edges of a finite graph can be written as a union of disjoint simple cycles if and only if every vertex has even degree. Thus, it is closely related to the theorem of that a finite graph has an Euler tour (a single non-simple cycle that covers the edges of the graph) if and only if it is connected and every vertex has even degree. Indeed, a representation of a graph as a union of simple cycles may be obtained from an Euler tour by repeatedly splitting the tour into smaller cycles whenever there is a repeated vertex. However, Veblen's theorem applies also to disconnected graphs, and can be generalized to infinite graphs in which every vertex has finite degree .
If a countably infinite graph G has no odd-degree vertices, then it may be written as a union of disjoint (finite) simple cycles if and only if every finite subgraph of G can be extended (by including more edges and vertices from G) to a finite Eulerian graph. In particular, every countably infinite graph with only one end and with no odd vertices can be written as a union of disjoint cycles .

https://en.wikipedia.org/wiki/P-adic%20gamma%20function | In mathematics, the p-adic gamma function Γp is a function of a p-adic variable analogous to the gamma function. It was first explicitly defined by , though pointed out that implicitly used the same function. defined a p-adic analog Gp of log Γ. had previously given a definition of a different p-adic analogue of the gamma function, but his function does not have satisfactory properties and is not used much.
Definition
The p-adic gamma function is the unique continuous function of a p-adic integer x (with values in ) such that
for positive integers x, where the product is restricted to integers i not divisible by p. As the positive integers are dense with respect to the p-adic topology in , can be extended uniquely to the whole of . Here is the ring of p-adic integers. It follows from the definition that the values of are invertible in ; this is because these values are products of integers not divisible by p, and this property holds after the continuous extension to . Thus . Here is the set of invertible p-adic integers.
Basic properties of the p-adic gamma function
The classical gamma function satisfies the functional equation for any . This has an analogue with respect to the Morita gamma function:
The Euler's reflection formula has its following simple counterpart in the p-adic case:
where is the first digit in the p-adic expansion of x, unless , in which case rather than 0.
Special values
and, in general,
At the Morita gamma function is related to the Legendre symbol :
It can also be seen, that hence as .
Other interesting special values come from the Gross–Koblitz formula, which was first proved by cohomological tools, and later was proved using more elementary methods. For example,
where denotes the square root with first digit 3, and denotes the square root with first digit 2. (Such specifications must always be done if we talk about roots.)
Another example is
where is the square root of in congruent to 1 modulo 3.
p-adic Raabe formula
The Raabe-formula for the classical Gamma function says that
This has an analogue for the Iwasawa logarithm of the Morita gamma function:
The ceiling function to be understood as the p-adic limit such that through rational integers.
Mahler expansion
The Mahler expansion is similarly important for p-adic functions as the Taylor expansion in classical analysis. The Mahler expansion of the p-adic gamma function is the following:
where the sequence is defined by the following identity:

https://en.wikipedia.org/wiki/De%20Donder%E2%80%93Weyl%20theory | In mathematical physics, the De Donder–Weyl theory is a generalization of the Hamiltonian formalism in the calculus of variations and classical field theory over spacetime which treats the space and time coordinates on equal footing. In this framework, the Hamiltonian formalism in mechanics is generalized to field theory in the way that a field is represented as a system that varies both in space and in time. This generalization is different from the canonical Hamiltonian formalism in field theory which treats space and time variables differently and describes classical fields as infinite-dimensional systems evolving in time.
De Donder–Weyl formulation of field theory
The De Donder–Weyl theory is based on a change of variables known as Legendre transformation. Let xi be spacetime coordinates, for i = 1 to n (with n = 4 representing 3 + 1 dimensions of space and time), and ya field variables, for a = 1 to m, and L the Lagrangian density
With the polymomenta pia defined as
and the De Donder–Weyl Hamiltonian function H defined as
the De Donder–Weyl equations are:
This De Donder-Weyl Hamiltonian form of field equations is covariant and it is equivalent to the Euler-Lagrange equations when the Legendre transformation to the variables pia and H is not singular. The theory is a formulation of a covariant Hamiltonian field theory which is different from the canonical Hamiltonian formalism and for n = 1 it reduces to Hamiltonian mechanics (see also action principle in the calculus of variations).
Hermann Weyl in 1935 has developed the Hamilton-Jacobi theory for the De Donder–Weyl theory.
Similarly to the Hamiltonian formalism in mechanics formulated using the symplectic geometry of phase space
the De Donder-Weyl theory can be formulated using the multisymplectic geometry or polysymplectic geometry and the geometry
of jet bundles.
A generalization of the Poisson brackets to the De Donder–Weyl theory
and the representation of De Donder–Weyl equations in terms of generalized Poisson brackets satisfying the Gerstenhaber algebra
was found by Kanatchikov in 1993.
History
The formalism, now known as De Donder–Weyl (DW) theory, was developed by Théophile De Donder and Hermann Weyl. Hermann Weyl made his proposal in 1934 being inspired by the work of Constantin Carathéodory, which in turn was founded on the work of Vito Volterra. The work of De Donder on the other hand started from the theory of integral invariants of Élie Cartan. The De Donder–Weyl theory has been a part of the calculus of variations since the 1930s and initially it found very few applications in physics. Recently it was applied in theoretical physics in the context of quantum field theory and quantum gravity.
In 1970, Jedrzej Śniatycki, the author of Geometric quantization and quantum mechanics, developed an invariant geometrical formulation of jet bundles, building on the work of De Donder and Weyl. In 1999 Igor Kanatchikov has shown that the De Donder–Weyl covariant Hamilt |

https://en.wikipedia.org/wiki/Crisis%20%28dynamical%20systems%29 | In applied mathematics and astrodynamics, in the theory of dynamical systems, a crisis is the sudden appearance or disappearance of a strange attractor as the parameters of a dynamical system are varied. This global bifurcation occurs when a chaotic attractor comes into contact with an unstable periodic orbit or its stable manifold. As the orbit approaches the unstable orbit it will diverge away from the previous attractor, leading to a qualitatively different behaviour. Crises can produce intermittent behaviour.
Grebogi, Ott, Romeiras, and Yorke distinguished between three types of crises:
The first type, a boundary or an exterior crisis, the attractor is suddenly destroyed as the parameters are varied. In the postbifurcation state the motion is transiently chaotic, moving chaotically along the former attractor before being attracted to a fixed point, periodic orbit, quasiperiodic orbit, another strange attractor, or diverging to infinity.
In the second type of crisis, an interior crisis, the size of the chaotic attractor suddenly increases. The attractor encounters an unstable fixed point or periodic solution that is inside the basin of attraction.
In the third type, an attractor merging crisis, two or more chaotic attractors merge to form a single attractor as the critical parameter value is passed.
Note that the reverse case (sudden appearance, shrinking or splitting of attractors) can also occur. The latter two crises are sometimes called explosive bifurcations.
While crises are "sudden" as a parameter is varied, the dynamics of the system over time can show long transients before orbits leave the neighbourhood of the old attractor. Typically there is a time constant τ for the length of the transient that diverges as a power law (τ ≈ |p − pc|γ) near the critical parameter value pc. The exponent γ is called the critical crisis exponent. There also exist systems where the divergence is stronger than a power law, so-called super-persistent chaotic transients.

With X and Y being a subset of the real numbers R, or X and Y ⊂ R, being respectively an input space X and an output space Y, we consider a training set:
of size m in drawn independently and identically distributed (i.i.d.) from an unknown distribution, here called "D". Then a learning algorithm is a function from into which maps a learning set S onto a function from the input space X to the output space Y. To avoid complex notation, we consider only deterministic algorithms. It is also assumed that the algorithm is symmetric with respect to S, i.e. it does not depend on the order of the elements in the training set. Furthermore, we assume that all functions are measurable and all sets are countable which does not limit the interest of the results presented here.
The loss of an hypothesis f with respect to an example is then defined as .
The empirical error of f can then be written as .

https://en.wikipedia.org/wiki/Artin%E2%80%93Verdier%20duality | In mathematics, Artin–Verdier duality is a duality theorem for constructible abelian sheaves over the spectrum of a ring of algebraic numbers, introduced by , that generalizes Tate duality.
It shows that, as far as etale (or flat) cohomology is concerned, the ring of integers in a number field behaves like a 3-dimensional mathematical object.
Statement
Let X be the spectrum of the ring of integers in a totally imaginary number field K, and F a constructible étale abelian sheaf on X. Then the Yoneda pairing
is a non-degenerate pairing of finite abelian groups, for every integer r.
Here, Hr(X,F) is the r-th étale cohomology group of the scheme X with values in F, and Extr(F,G) is the group of r-extensions of the étale sheaf G by the étale sheaf F in the category of étale abelian sheaves on X. Moreover, Gm denotes the étale sheaf of units in the structure sheaf of X.
proved Artin–Verdier duality for constructible, but not necessarily torsion sheaves. For such a sheaf F, the above pairing induces isomorphisms
where
Finite flat group schemes
Let U be an open subscheme of the spectrum of the ring of integers in a number field K, and F a finite flat commutative group scheme over U. Then the cup product defines a non-degenerate pairing
of finite abelian groups, for all integers r.
Here FD denotes the Cartier dual of F, which is another finite flat commutative group scheme over U. Moreover, is the r-th flat cohomology group of the scheme U with values in the flat abelian sheaf F, and is the r-th flat cohomology with compact supports of U with values in the flat abelian sheaf F.
The flat cohomology with compact supports is defined to give rise to a long exact sequence
The sum is taken over all places of K, which are not in U, including the archimedean ones. The local contribution Hr(Kv, F) is the Galois cohomology of the Henselization Kv of K at the place v, modified a la Tate:

https://en.wikipedia.org/wiki/Tate%20duality | In mathematics, Tate duality or Poitou–Tate duality is a duality theorem for Galois cohomology groups of modules over the Galois group of an algebraic number field or local field, introduced by and .
Local Tate duality
For a p-adic local field , local Tate duality says there is a perfect pairing of the finite groups arising from Galois cohomology:
where is a finite group scheme, its dual , and is the multiplicative group.
For a local field of characteristic , the statement is similar, except that the pairing takes values in . The statement also holds when is an Archimedean field, though the definition of the cohomology groups looks somewhat different in this case.
Global Tate duality
Given a finite group scheme over a global field , global Tate duality relates the cohomology of with that of using the local pairings constructed above. This is done via the localization maps
where varies over all places of , and where denotes a restricted product with respect to the unramified cohomology groups. Summing the local pairings gives a canonical perfect pairing
One part of Poitou-Tate duality states that, under this pairing, the image of has annihilator equal to the image of for .
The map has a finite kernel for all , and Tate also constructs a canonical perfect pairing
These dualities are often presented in the form of a nine-term exact sequence
Here, the asterisk denotes the Pontryagin dual of a given locally compact abelian group.
All of these statements were presented by Tate in a more general form depending on a set of places of , with the above statements being the form of his theorems for the case where contains all places of . For the more general result, see e.g.
.
Poitou–Tate duality
Among other statements, Poitou–Tate duality establishes a perfect pairing between certain Shafarevich groups. Given a global field , a set S of primes, and the maximal extension which is unramified outside S, the Shafarevich groups capture, broadly speaking, those elements in the cohomology of which vanish in the Galois cohomology of the local fields pertaining to the primes in S.
An extension to the case where the ring of S-integers is replaced by a regular scheme of finite type over was shown by .

https://en.wikipedia.org/wiki/Cardinal%20characteristic%20of%20the%20continuum | In the mathematical discipline of set theory, a cardinal characteristic of the continuum is an infinite cardinal number that may consistently lie strictly between (the cardinality of the set of natural numbers), and the cardinality of the continuum, that is, the cardinality of the set of all real numbers. The latter cardinal is denoted or . A variety of such cardinal characteristics arise naturally, and much work has been done in determining what relations between them are provable, and constructing models of set theory for various consistent configurations of them.
Background
Cantor's diagonal argument shows that is strictly greater than , but it does not specify whether it is the least cardinal greater than (that is, ). Indeed the assumption that is the well-known Continuum Hypothesis, which was shown to be consistent with the standard ZFC axioms for set theory by Kurt Godel and to be independent of it by Paul Cohen. If the Continuum Hypothesis fails and so is at least , natural questions arise about the cardinals strictly between and , for example regarding Lebesgue measurability. By considering the least cardinal with some property, one may get a definition for an uncountable cardinal that is consistently less than . Generally one only considers definitions for cardinals that are provably greater than and at most as cardinal characteristics of the continuum, so if the Continuum Hypothesis holds they are all equal to .
Examples
As is standard in set theory, we denote by the least infinite ordinal, which has cardinality ; it may be identified with the set of all natural numbers.
A number of cardinal characteristics naturally arise as cardinal invariants for ideals which are closely connected with the structure of the reals, such as the ideal of Lebesgue null sets and the ideal of meagre sets.
non(N)
The cardinal characteristic non() is the least cardinality of a non-measurable set; equivalently, it is the least cardinality of a set that is not a Lebesgue null set.
Bounding number and dominating number
We denote by the set of functions from to . For any two functions and we denote by the statement that for all but finitely many . The bounding number is the least cardinality of an unbounded set in this relation, that is,
The dominating number is the least cardinality of a set of functions from to such that every such function is dominated by (that is, ) a member of that set, that is,
Clearly any such dominating set is unbounded, so is at most , and a diagonalisation argument shows that . Of course if this implies that , but Hechler has shown that it is also consistent to have strictly less than .
Splitting number and reaping number
We denote by the set of all infinite subsets of . For any , we say that splits if both and are infinite. The splitting number is the least cardinality of a subset of such that for all , there is some such that splits . That is,

https://en.wikipedia.org/wiki/Russians%20in%20Taiwan | Russians in Taiwan form a small community. As of August 2021, statistics of Taiwan's National Immigration Agency (NIA) showed 593 Russians holding valid Alien Resident Certificates. Informal estimates claim that their population may be as large as one thousand people.
History
Some Russians from Shanghai and Xinjiang fled the establishment of the People's Republic of China and resettled in Taiwan in 1949. One cultural institution among the Russian community in Taiwan that survives from those days is the Astoria Confectionery and Cafe near Taipei Railway Station, the first Russian-style eatery on the whole island. Founded in 1949 by five Russian émigrés from Shanghai, it continues operating today with an early local business partner as the sole owner.
In recent years, the Representative Office for the Moscow-Taipei Coordination Commission on Economic and Cultural Cooperation has been active in promoting academic and professional exchanges between the two countries. According to NIA statistics, 174 Russian students studied at institutions in Taiwan, and 20 were employed as instructors; 21 were housewives, 28 were children under 15 years of age, and the remaining 120 engaged in other types of work. Unlike in other European communities, men are relatively scarce, with a sex ratio of 1.36 women for every man.

https://en.wikipedia.org/wiki/Kernel%20Fisher%20discriminant%20analysis | In statistics, kernel Fisher discriminant analysis (KFD), also known as generalized discriminant analysis and kernel discriminant analysis, is a kernelized version of linear discriminant analysis (LDA). It is named after Ronald Fisher.
Linear discriminant analysis
Intuitively, the idea of LDA is to find a projection where class separation is maximized. Given two sets of labeled data, and , we can calculate the mean value of each class, and , as
where is the number of examples of class . The goal of linear discriminant analysis is to give a large separation of the class means while also keeping the in-class variance small. This is formulated as maximizing, with respect to , the following ratio:
where is the between-class covariance matrix and is the total within-class covariance matrix:
The maximum of the above ratio is attained at
as can be shown by the Lagrange multiplier method (sketch of proof):
Maximizing is equivalent to maximizing
subject to
This, in turn, is equivalent to maximizing , where is the Lagrange multiplier.
At the maximum, the derivatives of with respect to and must be zero. Taking yields
which is trivially satisfied by and
Extending LDA
To extend LDA to non-linear mappings, the data, given as the points can be mapped to a new feature space, via some function In this new feature space, the function that needs to be maximized is
where
and
Further, note that . Explicitly computing the mappings and then performing LDA can be computationally expensive, and in many cases intractable. For example, may be infinitely dimensional. Thus, rather than explicitly mapping the data to , the data can be implicitly embedded by rewriting the algorithm in terms of dot products and using kernel functions in which the dot product in the new feature space is replaced by a kernel function,.
LDA can be reformulated in terms of dot products by first noting that will have an expansion of
the form
Then note that
where
The numerator of can then be written as:
Similarly, the denominator can be written as
with the component of defined as is the identity matrix, and the matrix with all entries equal to . This identity can be derived by starting out with the expression for and using the expansion of and the definitions of and
With these equations for the numerator and denominator of , the equation for can be rewritten as
Then, differentiating and setting equal to zero gives
Since only the direction of , and hence the direction of matters, the above can be solved for as
Note that in practice, is usually singular and so a multiple of the identity is added to it
Given the solution for , the projection of a new data point is given by

https://en.wikipedia.org/wiki/Generalized%20integer%20gamma%20distribution | In probability and statistics, the generalized integer gamma distribution (GIG) is the distribution of the sum of independent
gamma distributed random variables, all with integer shape parameters and different rate parameters. This is a special case of the generalized chi-squared distribution. A related concept is the generalized near-integer gamma distribution (GNIG).
Definition
The random variable has a gamma distribution with shape parameter and rate parameter if its probability density function is
and this fact is denoted by
Let , where be independent random variables, with all being positive integers and all different. In other words, each variable has the Erlang distribution with different shape parameters. The uniqueness of each shape parameter comes without loss of generality, because any case where some of the are equal would be treated by first adding the corresponding variables: this sum would have a gamma distribution with the same rate parameter and a shape parameter which is equal to the sum of the shape parameters in the original distributions.
Then the random variable Y defined by
has a GIG (generalized integer gamma) distribution of depth with shape parameters and rate parameters . This fact is denoted by
It is also a special case of the generalized chi-squared distribution.
Properties
The probability density function and the cumulative distribution function of Y are respectively given by

Alternative expressions are available in the literature on generalized chi-squared distribution, which is a field wherecomputer algorithms have been available for some years.
Generalization
The GNIG (generalized near-integer gamma) distribution of depth is the distribution of the random variable

Applications
The GIG and GNIG distributions are the basis for the exact and near-exact distributions of a large number of likelihood ratio test statistics and related statistics used in multivariate analysis. More precisely, this application is usually for the exact and near-exact distributions of the negative logarithm of such statistics. If necessary, it is then easy, through a simple transformation, to obtain the corresponding exact or near-exact distributions for the corresponding likelihood ratio test statistics themselves.
The GIG distribution is also the basis for a number of wrapped distributions in the wrapped gamma family.

https://en.wikipedia.org/wiki/Michael%20Cates | Michael Elmhirst Cates (born 5 May 1961) is a British physicist. He is the 19th Lucasian Professor of Mathematics at the University of Cambridge and has held this position since 1 July 2015.
He was previously Professor of Natural Philosophy at the University of Edinburgh, and has held a Royal Society Research Professorship since 2007.
His work focuses on the theory of soft matter, such as polymers, colloids, gels, liquid crystals, and granular material. A recurring goal of his research is to create a mathematical model that predicts the stress in a flowing material as a functional of the flow history of that material. Such a mathematical model is called a constitutive equation. He has worked on theories of active matter, particularly dense suspensions of self-propelled particles which can include motile bacteria. His interests also include fundamental field theories of active systems in which time-reversal symmetry (T-symmetry, and more generally, CPT symmetry) is absent. Such theories are characterised by non-zero steady-state entropy production.
At Edinburgh, Cates was the Principal Investigator of an EPSRC Programme Grant, awarded in 2011, entitled Design Principles for New Soft Materials. On his departure for Cambridge, Cait MacPhee took over as Principal Investigator. Cates remains an Honorary Professor at Edinburgh.
Early life
Cates was born on 5 May 1961. He read Natural Sciences and earned a PhD at Trinity College, Cambridge, in 1985, where he studied with Sam Edwards.
Academic career
Cates was a research fellow and lecturer at the Cavendish Laboratory, University of Cambridge before moving to Edinburgh in 1995.
Honours
Cates won the Bingham Medal of the US Society of Rheology in 2016. He had previously won the 2013 Weissenberg Award of the European Society of Rheology and the
2009 Gold Medal of the British Society of Rheology. He was awarded the 2009 Dirac Prize by the Institute of Physics. He won the 1991 Maxwell Medal and Prize. He has served as an elected member of the Council of the Royal Society, and chairs the International Scientific Committee of ESPCI ParisTech. He was an honorary fellow of Trinity College, Cambridge from 2013 until 2016, when he became instead a senior research fellow.
He was also elected a member of the National Academy of Engineering in 2019 for research on the rheology, dynamics, and thermodynamics of complex fluids, and for scientific leadership in the European Community.

https://en.wikipedia.org/wiki/Niven%27s%20theorem | In mathematics, Niven's theorem, named after Ivan Niven, states that the only rational values of θ in the interval 0° ≤ θ ≤ 90° for which the sine of θ degrees is also a rational number are:
In radians, one would require that 0 ≤ x ≤ /2, that x/ be rational, and that sinx be rational. The conclusion is then that the only such values are sin 0 = 0, sin /6 = 1/2, and sin /2 = 1.
The theorem appears as Corollary 3.12 in Niven's book on irrational numbers.
The theorem extends to the other trigonometric functions as well. For rational values of θ, the only rational values of the sine or cosine are 0, ±1/2, and ±1; the only rational values of the secant or cosecant are ±1 and ±2; and the only rational values of the tangent or cotangent are 0 and ±1.
History
Niven's proof of his theorem appears in his book Irrational Numbers. Earlier, the theorem had been proven by D. H. Lehmer and J. M. H. Olmstead. In his 1933 paper, Lehmer proved the theorem for cosine by proving a more general result. Namely, Lehmer showed that for relatively prime integers and with , the number is an algebraic number of degree , where denotes Euler's totient function. Because rational numbers have degree 1, we must have and therefore the only possibilities are 1, 2, 3, 4, or 6. Next, he proved a corresponding result for sine using the trigonometric identity . In 1956, Niven extended Lehmer's result to the other trigonometric functions. Other mathematicians have given new proofs in subsequent years.
