Speed of random walks
If you have a question about this talk, please contact Julia Blackwell.
How fast does a random walk on a graph escape from its starting point? In this survey talk, I will consider this question in a variety of settings:
Simple RW on Galton-Watson trees, where speed can be computed
RW on lamplighter groups: The Kaimanovich-Vershik Theorem
Which escape exponents are possible for RW on groups?
Benjamini-Lyons-Schramm conjecture: percolation preserves speed of RW
The effect of bias for RW on trees and on groups
Surprisingly, the expected distance from the starting point can be non-monotone, even when starting at the stationary distribution and the walk has holding probability 1/2.
*The square root lower bound on groups: Can it be proved beyond the inverse spectral gap?
