GEOMETRIE

Geometric group theory in connection with topology is my main research interest. The subject of my current research are the combinatorics of non-affine Coxeter groups within the context of my PhD studies.

Previously, I wrote my Bachelor and Master thesis on the local structure of locally compact groups and on a geometric proof of the strong Hanna Neumann conjecture.The former deals mainly with local splitting properties of these groups.
