Counting problems for Green functions on hyperbolic groups
Analysis and Geometry Seminar
7th November 2024, 3:00 pm – 4:00 pm
Fry Building, 2.04
Suppose we run a finitely supported random walk on a group G. The corresponding Green function encodes information about the asymptotic properties of this walk. In this talk we discuss counting problems related to Green functions on hyperbolic groups. These counting results include an analogue of the orbital counting problem and a counting central limit theorem comparing two random walks.
