GRAW02 - Computational and algorithmic methods

This talk is devoted to the symbolic enumeration of conjugacy classes in infinite families of finite p-groups attached to a given unipotent algebraic group. I will report on recent joint work with Christopher Voll which solves this problem for unipotent groups associated with graphs. As a by-product, we obtain polynomiality results in the spirit of Higman's conjecture on class numbers of unitriangular matrix groups.
