Cohen-Macaulayness of modules of covariants
If G is a reductive group and U, W are two finite dimensional representations then M(U)=(U otimes Sym(W))^G is a so-called module of covariants over the invariant ring R=Sym(W)^G. It is a natural question the ask when M(U) is a Cohen-Macaulay module, or more generally, to understand its local cohomology. In the talk we will give an introduction to these problems.
