Title:  A generalization of Dowling lattices

Abstract:   We are interested in certain arrangements of subvarieties on which a wreath product group acts. We give a combinatorial description of its poset of layers (connected components of intersections) as a generalization of a Dowling lattice. While these posets are not in general lattices, they still share several nice properties with Dowling and partition lattices. This combinatorial structure is an aid in understanding the cohomology of the complement as a representation of the group. Joint work with Nir Gadish.
