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…

Vector Fields and Luna Strata

Gerald W. Schwarz

Let V be a G-module where G is a complex reductive group. Let Z:=V//G denote the categorical quotient. One can ask if the Luna stratification of Z is intrinsic. That is, if phi : Z…

Reduced invariant sets

Gerald W. Schwarz

Let K be a compact Lie group and W a finite-dimensional real K-module. Let X be a K-stable real algebraic subset of W. Let I(X) denote the ideal of X in R[W] and let I_K(X) be the…
