This is based on joint work with Zhiwei Yun. Let g be the Lie algebra of a reductive group G. We are interested in computing the intersection cohomology of the nilpotent G-orbits in g with coefficients in various local systems. We are also interested in the analogous problem in the Z/m graded case.
