Application of Multihomogeneous Covariants to the Essential Dimension of Finite Groups

Roland Lötscher

We investigate essential dimension of finite groups over arbitrary fields and give a systematic treatment of multihomogenization, introduced by H.Kraft, G.Schwarz and the author. W…

A Generalized Composition of Quadratic Forms based on Quadratic Pairs

Roland Lötscher

For quadratic spaces which represent 1 there is a characterization of hermitian compositions in the language of algebras-with-involutions using the even Clifford algebra. We extend…

Compression of Finite Group Actions and Covariant Dimension, II

Hanspeter Kraft, Roland Lötscher, Gerald W. Schwarz

Let be a finite group and an equivariant morphism of finite dimensional -modules. We say that is faithful if acts faithfully on . The covariant dim…
