For zoom details please contact T. Barthel, V. Ozornova, A. Ray, P. Teichner.
In this talk we will focus on trying to understand the geometry and topology of certain non-compact finite volume hyperbolic n-manifolds with n > 3 (indeed we will mainly focus on n=4). One particular aspect we will focus on is the structure of co-dimension 1 totally geodesic submanifolds in these manifolds.
