Van Kampen's embedding obstruction for discrete groups

Mladen Bestvina, Michael Kapovich, Bruce Kleiner

We give a lower bound to the dimension of a contractible manifold on which a given group can act properly discontinuously. In particular, we show that the -fold product of nonab…

Coarse Alexander duality and duality groups

Michael Kapovich, Bruce Kleiner

We study discrete group actions on coarse Poincare duality spaces, e.g. acyclic simplicial complexes which admit free cocompact group actions by Poincare duality groups. When G is…

On normal subgroups in the fundamental groups of complex surfaces

Michael Kapovich

We show that for each aspherical compact complex surface whose fundamental group fits into a short exact sequence where is a compact…
