Geometric Group Theory Seminar
Title: Growth Tightness of Groups with Contracting Elements and Confined Subgroups
Speaker: Lihuang Ding
University: Peking University
Abstract:
Recall that for a hyperbolic group, the quotient group of any infinite normal subgroup has strictly smaller growth rate.Group action with contracting elements is a generalization of a hyperbolic group action. In this talk, we will present a generalization of the growth tightness theorem in group with contracting elements. We will also discuss the growth of confined subgroups. This is joint work with Wenyuan Yang.
