When does the zero fiber of the moment map have rational singularities?

Hans-Christian Herbig, Gerald W. Schwarz, Christopher Seaton

Let $G$ be a complex reductive group and $V$ a $G$ -module. There is a natural moment mapping $μ : V \oplus V^{*} \to g^{*}$ and we denote $μ^{- 1} (0)$ (the shell) by $N_{V}$ .…

Representations With a Reduced Null Cone

Hanspeter Kraft, Gerald W. Schwarz

Let G be a complex reductive group and V a G-module. Let π: V \to V//G be the quotient morphism and set N(V) = π^{-1}(π(0)). We consider the following question. Is the null cone N(…

Jet schemes and invariant theory

Andrew R. Linshaw, Gerald W. Schwarz, Bailin Song

Let $G$ be a complex reductive group and $V$ a $G$ -module. Then the $m$ th jet scheme $G_{m}$ acts on the $m$ th jet scheme $V_{m}$ for all $m \geq 0$ . We are interested in the invariant…

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…
