über das Thema:
| Abstract: |
| There is the problem, whether for a given virtually torsionfree discrete group Gamma there exists a cocompact proper topological Gamma-manifold, which is equivariantly homotopy equivalent to the classifying space for proper actions. It is related to Nielsen's Realization and to the problem of Brown, whether there is a $d$-dimensional model for the classifying space for proper actions, if the underlying group has virtually cohomological dimension d. Assuming that the expected manifold model has a zero-dimensional singular set, we solve the problem in the Poincare category and obtain new results about Brown's problem under certain conditions concerning the underlying group, for instance if it is hyperbolic. Then, together with James Davis, we will deal with this on the level of topological manifolds. |
