On Effective Witt Decomposition and Cartan-dieudonné Theorem
Let K be a number field, and let F be a symmetric bilinear form in 2N variables over K. Let Z be a subspace of K . A classical theorem of Witt states that the bilinear space (Z,F ) can be decomposed into an orthogonal sum of hyperbolic planes, singular, and anisotropic components. We prove the existence of such a decomposition of small height, where all bounds on height are explicit in terms of...
متن کاملComputing the Wedderburn decomposition of group algebras by the Brauer-Witt theorem
We present an alternative constructive proof of the Brauer–Witt theorem using the so-called strongly monomial characters that gives rise to an algorithm for computing the Wedderburn decomposition of semisimple group algebras of finite groups.
متن کاملOn Seymour’s Decomposition Theorem
Let M be a class of matroids closed under minors and isomorphism. Let M be a 3-connected matroid in M with an N-minor and let N have an exact k-separation (A, B). If there exists a k-separation (X ,Y ) of M such that A ⊆ X and B ⊆ Y , we say the k-separation (A, B) of N is induced in M. In this paper we give new sufficient conditions to determine if an exact k-separation of N is induced inM.
متن کاملQuadratic Pairs in Characteristic 2 and the Witt Cancellation Theorem
We define the orthogonal sum of quadratic pairs and we show that there is no Witt cancellation theorem for this operation in characteristic 2. 1. Introduction. Quadratic pairs on central simple algebras were defined in [5]. They play the same role for quadratic forms as involutions for symmetric or skew-symmetric bilinear forms. In particular, they can be used to define twisted orthogonal group...
متن کاملPoincaré ’ S Proof of the so - Called Birkhoff - Witt Theorem
In honor of the 100th birthday of the article, " Sur les groupes continus " Abstract: A methodical analysis of the research related to the article , " Sur les groupes continus " , of Henri Poincaré reveals many historical misconceptions and inaccuracies regarding his contribution to Lie theory. A thorough reading of this article confirms the precedence of his discovery of many important concept...
