https://en.wikipedia.org/wiki/D%27Alembert%27s%20equation
In mathematics, d'Alembert's equation is a first order nonlinear ordinary differential equation, named after the French mathematician Jean le Rond d'Alembert. The equation reads as where . After differentiating once, and rearranging we have The above equation is linear. When , d'Alembert's equation is reduced to Clai...
https://en.wikipedia.org/wiki/Interchange%20of%20limiting%20operations
In mathematics, the study of interchange of limiting operations is one of the major concerns of mathematical analysis, in that two given limiting operations, say L and M, cannot be assumed to give the same result when applied in either order. One of the historical sources for this theory is the study of trigonometric s...
https://en.wikipedia.org/wiki/Pullback%20attractor
In mathematics, the attractor of a random dynamical system may be loosely thought of as a set to which the system evolves after a long enough time. The basic idea is the same as for a deterministic dynamical system, but requires careful treatment because random dynamical systems are necessarily non-autonomous. This req...

In computational geometry, the minimum bounding rectangle (MBR), also known as bounding box (BBOX) or envelope, is an expression of the maximum extents of a two-dimensional object (e.g. point, line, polygon) or set of objects within its coordinate system; in other words , , , . The MBR is a 2-dimensional case of the m...
https://en.wikipedia.org/wiki/Constraint%20%28mathematics%29
In mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. There are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. The set of candidate solutions that satisfy all constraints is called the feasible set. Example ...

In mathematics, the Lehmer mean of a tuple of positive real numbers, named after Derrick Henry Lehmer, is defined as: The weighted Lehmer mean with respect to a tuple of positive weights is defined as: The Lehmer mean is an alternative to power means for interpolating between minimum and maximum via arithmetic mean...
https://en.wikipedia.org/wiki/Stolarsky%20mean
In mathematics, the Stolarsky mean is a generalization of the logarithmic mean. It was introduced by Kenneth B. Stolarsky in 1975. Definition For two positive real numbers x, y the Stolarsky Mean is defined as: Derivation It is derived from the mean value theorem, which states that a secant line, cutting the graph of...

According to the official statistics, one gymnast, Adolf Spinnler, and one wrestler, Gustav Thiefenthaler, from Switzerland competed at the 1904 Summer Olympics in St. Louis, United States. But there were more athletes with Swiss roots at the Olympics: Andreas Kempf competed in three gymnastics events, finishing 8th i...

https://en.wikipedia.org/wiki/Period%20%28algebraic%20geometry%29
In algebraic geometry, a period is a number that can be expressed as an integral of an algebraic function over an algebraic domain. Sums and products of periods remain periods, such that the periods form a ring. Maxim Kontsevich and Don Zagier gave a survey of periods and introduced some conjectures about them. Peri...

https://en.wikipedia.org/wiki/Compact%20convergence
In mathematics compact convergence (or uniform convergence on compact sets) is a type of convergence that generalizes the idea of uniform convergence. It is associated with the compact-open topology. Definition Let be a topological space and be a metric space. A sequence of functions , is said to converge compac...
https://en.wikipedia.org/wiki/Normal%20convergence
In mathematics normal convergence is a type of convergence for series of functions. Like absolute-convergence, it has the useful property that it is preserved when the order of summation is changed. History The concept of normal convergence was first introduced by René Baire in 1908 in his book Leçons sur les théor...
https://en.wikipedia.org/wiki/Baer%20ring
In abstract algebra and functional analysis, Baer rings, Baer *-rings, Rickart rings, Rickart *-rings, and AW*-algebras are various attempts to give an algebraic analogue of von Neumann algebras, using axioms about annihilators of various sets. Any von Neumann algebra is a Baer *-ring, and much of the theory of proje...

In algebra, the zero object of a given algebraic structure is, in the sense explained below, the simplest object of such structure. As a set it is a singleton, and as a magma has a trivial structure, which is also an abelian group. The aforementioned abelian group structure is usually identified as addition, and the on...
