51Wess-Zumino-Witten model — In theoretical physics and mathematics, the Wess Zumino Witten (WZW) model, also called the Wess Zumino Novikov Witten model, is a simple model of conformal field theory whose solutions are realized by affine Kac Moody algebras. It is named after …
52Butcher group — In mathematics, the Butcher group, named after the New Zealand mathematician John C. Butcher by Hairer Wanner (1974), is an infinite dimensional group first introduced in numerical analysis to study solutions of non linear ordinary differential… …
53Symplectic group — For finite groups with all characteristc abelian subgroups cyclic, see group of symplectic type. Group theory …
54Covering group — This article is about topological covering group. For algebraic covering group, see universal perfect central extension. In mathematics, a covering group of a topological group H is a covering space G of H such that G is a topological group and… …
55Matrix (mathematics) — Specific elements of a matrix are often denoted by a variable with two subscripts. For instance, a2,1 represents the element at the second row and first column of a matrix A. In mathematics, a matrix (plural matrices, or less commonly matrixes)… …
56Adjoint representation — In mathematics, the adjoint representation (or adjoint action) of a Lie group G is the natural representation of G on its own Lie algebra. This representation is the linearized version of the action of G on itself by conjugation.Formal… …
57Baum–Connes conjecture — In mathematics, specifically in operator K theory, the Baum ndash;Connes conjecture suggests a link between the C* algebra of a group and the K homology of the corresponding classifying space of proper actions of that group.It thus sets up a… …
58Schriften von Charles Sanders Peirce — Das nachfolgende Verzeichnis der Schriften von Charles Sanders Peirce dient als Ergänzung zum Verzeichnis der Werke von Peirce im Hauptartikel. Inhaltsverzeichnis 1 Vorbemerkung 2 Collected Papers 2.1 Vol. I. Principles of Philosophy …
59Orientation (vector space) — See also: orientation (geometry) The left handed orientation is shown on the left, and the right handed on the right. In mathematics, orientation is a notion that in two dimensions allows one to say when a cycle goes around clockwise or… …
60Torus — Not to be confused with Taurus (disambiguation). This article is about the surface and mathematical concept of a torus. For other uses, see Torus (disambiguation). A torus As the distance to th …
