Compression of Finite Group Actions and Covariant Dimension, II

Hanspeter Kraft, Roland Lötscher, Gerald W. Schwarz

Let $G$ be a finite group and $ϕ : V \to W$ an equivariant morphism of finite dimensional $G$ -modules. We say that $ϕ$ is faithful if $G$ acts faithfully on $ϕ (V)$ . The covariant dim…

Real double coset spaces and their invariants

Aloysius G. Helminck, Gerald W. Schwarz

Let G be a real form of a complex reductive group. Suppose that we are given involutions σand θof G. Let H=G^σdenote the fixed group of σand let K=G^θdenote the fixed group of θ. W…

Isomorphisms preserving invariants

Gerald W. Schwarz

Let $V$ and $W$ be finite dimensional real vector spaces and let $G\subset\GL(V)$ and $H\subset\GL(W)$ be finite subgroups. Assume for simplicity that the actions contain no reflec…
