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…

Linear maps preserving invariants

Gerald W. Schwarz

Let $G\subset\GL(V)$ be a complex reductive group. Let $G^{'}$ denote $\{ϕ\in\GL(V)\mid p\circϕ=p\text{for all} p\in\C[V]^G\}$. We show that, in general, $G^{'} = G$ . In case $G$ is the ad…

Cartan decomposition of the moment map

P. Heinzner, G. W. Schwarz

We investigate a class of actions of real Lie groups on complex spaces. Using moment map techniques we establish the existence of a quotient and a version of Luna's slice theorem a…
