It is also called MacMahon's net after Percy Alexander MacMahon, who depicted it in his 1921 p...
https://en.wikipedia.org/wiki/Rational%20point
In number theory and algebraic geometry, a rational point of an algebraic variety is a point whose coordinates belong to a given field. If the field is not mentioned, the field of rational numbers is generally understood. If the field is the field of real numbers, a rational point is more commonly called a real point. ...
https://en.wikipedia.org/wiki/Weil%20cohomology%20theory
In algebraic geometry, a Weil cohomology or Weil cohomology theory is a cohomology satisfying certain axioms concerning the interplay of algebraic cycles and cohomology groups. The name is in honor of André Weil. Any Weil cohomology theory factors uniquely through the category of Chow motives, but the category of Chow...

According to the French National Institute of Statistics INSEE, the 2021 census counted nearly 7 million immigrants (foreign-born people) in France, representing 10.3% of the total population. This is a decrease from INSEE statistics in 2018 in which there were 9 million immigrants (foreign-born people) in France, whic...
https://en.wikipedia.org/wiki/Fluent%20calculus
The fluent calculus is a formalism for expressing dynamical domains in first-order logic. It is a variant of the situation calculus; the main difference is that situations are considered representations of states. A binary function symbol is used to concatenate the terms that represent facts that hold in a situation. ...
https://en.wikipedia.org/wiki/Blattner%27s%20conjecture
In mathematics, Blattner's conjecture or Blattner's formula is a description of the discrete series representations of a general semisimple group G in terms of their restricted representations to a maximal compact subgroup K (their so-called K-types). It is named after Robert James Blattner, despite not being formulate...

https://en.wikipedia.org/wiki/Solvable%20Lie%20algebra
In mathematics, a Lie algebra is solvable if its derived series terminates in the zero subalgebra. The derived Lie algebra of the Lie algebra is the subalgebra of , denoted that consists of all linear combinations of Lie brackets of pairs of elements of . The derived series is the sequence of subalgebras If the der...
https://en.wikipedia.org/wiki/Final%20stellation%20of%20the%20icosahedron
In geometry, the complete or final stellation of the icosahedron is the outermost stellation of the icosahedron, and is "complete" and "final" because it includes all of the cells in the icosahedron's stellation diagram. That is, every three intersecting face planes of the icosahedral core intersect either on a vertex ...
https://en.wikipedia.org/wiki/Weil%20reciprocity%20law
In mathematics, the Weil reciprocity law is a result of André Weil holding in the function field K(C) of an algebraic curve C over an algebraically closed field K. Given functions f and g in K(C), i.e. rational functions on C, then f((g)) = g((f)) where the notation has this meaning: (h) is the divisor of the functio...

Joseph Henry Maclagan Wedderburn FRSE FRS (2 February 1882 – 9 October 1948) was a Scottish mathematician, who taught at Princeton University for most of his career. A significant algebraist, he proved that a finite division algebra is a field, and part of the Artin–Wedderburn theorem on simple algebras. He also worked...

https://en.wikipedia.org/wiki/Penrose%20graphical%20notation
In mathematics and physics, Penrose graphical notation or tensor diagram notation is a (usually handwritten) visual depiction of multilinear functions or tensors proposed by Roger Penrose in 1971. A diagram in the notation consists of several shapes linked together by lines. The notation widely appears in modern quan...
https://en.wikipedia.org/wiki/Idempotent%20matrix
In linear algebra, an idempotent matrix is a matrix which, when multiplied by itself, yields itself. That is, the matrix is idempotent if and only if . For this product to be defined, must necessarily be a square matrix. Viewed this way, idempotent matrices are idempotent elements of matrix rings. Example Examples ...
