Generators and relations for the unitary group of a skew hermitian form over a local ring

James Cruickshank, Fernando Szechtman

Let $(S, *)$ be an involutive local ring and let $U (2 m, S)$ be the unitary group associated to a nondegenerate skew hermitian form defined on a free $S$ -module of rank $2 m$ . A presen…

Hermitian and skew hermitian forms over local rings

James Cruickshank, Rachel Quinlan, Fernando Szechtman

We study the classification problem of possibly degenerate hermitian and skew hermitian bilinear forms over local rings where 2 is a unit.
