Factorization of Symmetric Matrices and Actions on \Sigma_k

Algebraic Geometry 2007-05-23 v1 Rings and Algebras

Abstract

In this note, firstly we give an easy proof of the factorization of symmetric matrices (see [Mos] math-ph/0203023), then we use it to prove the well-known fact that the automorphism group of a non-degenerate symmetric bilinear form acts transitively on the locus of isotropic subspaces \Sigma_k.
