1Paire de matrices commutantes — En mathématiques, une paire de matrices commutantes est un couple (A,B) de matrices carrées à coefficients dans un corps commutatif qui commutent, c est à dire que AB = BA. L étude des paires de matrices commutantes a des aspects tout à fait… …

3Quasidihedral group — In mathematics, the quasi dihedral groups and semi dihedral groups are non abelian groups of order a power of 2. For every positive integer n greater than or equal to 4, there are exactly four isomorphism classes of nonabelian groups of order 2n… …
4Frobenius group — In mathematics, a Frobenius group is a transitive permutation group on a finite set, such that no non trivial elementfixes more than one point and some non trivial element fixes a point. They are named after F. G. Frobenius. Structure The… …
5Jordan normal form — In linear algebra, a Jordan normal form (often called Jordan canonical form)[1] of a linear operator on a finite dimensional vector space is an upper triangular matrix of a particular form called Jordan matrix, representing the operator on some… …
6Margulis lemma — In mathematics, the Margulis lemma (named after Grigory Margulis) is a result about discrete subgroups of isometries of a symmetric space (e.g. the hyperbolic n space), or more generally a space of non positive curvature. Theorem: Let S be a… …
7Regular p-group — In mathematics, especially in the field of group theory, the concept of regular p group captures some of the more important properties of abelian p groups, but is general enough to include most small p groups. The concept was first described by… …
