If you have a question about this talk, please contact HoD Secretary, DPMMS. 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:
RW on lamplighter groups: The Kaimanovich-Vershik Theorem
Benjamini-Lyons-Schramm conjecture: percolation preserves speed of RW
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?
