Abstract: Classifying groups upto quasiisometry is a classical task in geometric group theory. Even in the nice class of Coxeter groups, this classification is widely open in general.
The goal of this talk is to present a visual algorithm to give a lower bound on the conformal dimension of the boundary of a hyperbolic, oneended Coxeter group and to show how this contributes to the quasiisometry classification. All necessary concepts will be introduced.
This is ongoing joint work with Tullia Dymarz, Heejoung Kim, Anne Thomas, and Hanh Vo.
