This paper gives characterizations for the largest non-vanishing degree of the local cohomology modules of a graded ring S in terms of a reduction of S and of q the associated graded ring of an ideal I in terms of any reduction of I. As a consequence, this invariant can be computed explicitly for th
Let G be a connected reductive algebraic group over an algebraically closed field of characteristic zero and let W, U be two finite dimensional representations of G. In this paper we compute the local cohomology of (U SW ) G provided a certain relatively weak technical condition is true.
