decomposable representation
1Representation theory — This article is about the theory of representations of algebraic structures by linear transformations and matrices. For the more general notion of representations throughout mathematics, see representation (mathematics). Representation theory is… …
2Group representation — In the mathematical field of representation theory, group representations describe abstract groups in terms of linear transformations of vector spaces; in particular, they can be used to represent group elements as matrices so that the group… …
3Lie algebra representation — Lie groups …
4Exterior algebra — In mathematics, the exterior product or wedge product of vectors is an algebraic construction generalizing certain features of the cross product to higher dimensions. Like the cross product, and the scalar triple product, the exterior product of… …
5Direct integral — In mathematics and functional analysis a direct integral is a generalization of the concept of direct sum. The theory is most developed for direct integrals of Hilbert spaces and direct integrals of von Neumann algebras. The concept was… …
6Spinor — In mathematics and physics, in particular in the theory of the orthogonal groups (such as the rotation or the Lorentz groups), spinors are elements of a complex vector space introduced to expand the notion of spatial vector. Unlike tensors, the… …
7COURBES ALGÉBRIQUES — En fondant la géométrie analytique, Descartes avait substitué au plan de la géométrie d’Euclide l’ensemble R2 des couples de nombres réels et, de ce fait, à la notion de courbe, celle d’équation. La construction d’un point, puis la détermination… …
8Chordal graph — A cycle (black) with two chords (green). As for this part, the graph is chordal. However, removing one green edge would result in a non chordal graph. Indeed, the other green edge with three black edges would form a cycle of length four with no… …
9CYBERNÉTIQUE - Principe — Norbert Wiener définissait la cybernétique comme l’«étude de la commande et de la communication chez l’animal et dans la machine». Les progrès accomplis dans les domaines de l’automatique et de l’informatique ont conduit à adopter une définition… …
10Analyse Entrée-sortie — L Analyse entrée sortie ou analyse entrées sorties, est une modélisation économique utilisant le tableau entrées sorties (TES) permettant de prévoir l influence des changements dans un secteur d activité particulier ou des changements de… …
