Topology Seminar (Introductory Talk): Random walks on groups with negative curvature
Seminar | April 12 | 2:10-3 p.m. | 736 Evans Hall
Joseph Maher, CUNY
We will give a gentle introduction to random walks on groups satisfying various types of negative curvature conditions. A simple example is the nearest neighbour random walk on the 4-valent tree, also known as the Cayley graph of the free group on two generators. A typical random walk moves away from the origin at linear speed, and converges to one of the ends of the tree. We will discuss how to generalize this result to more general settings, such as hyperbolic groups, or acylindrical groups. This is joint work with Giulio Tiozzo.
