Tuesday, October 19 2010 talks: Denis Osin

Denis Osin of Vanderbilt University will be speaking on:

Title: Dehn Filling in relatively hyperbolic groups.

Abstract: I will talk about a group theoretic analogue of Dehn surgery on 3-dimensional manifolds. The main result is a generalization of the Thurston’s hyperbolic Dehn filling theorem. Various applications to algebraic, algorithmic, geometric, and model theoretic questions will be discussed.
