Simple random walk on supercritical causal maps

Presented by: 
Thomas Budzinski ENS - Paris, Université Paris-Sud 11
Monday 16th July 2018 - 14:35 to 14:55
INI Seminar Room 1
We study the simple random walk on supercritical causal maps, obtained from a supercritical Galton-Watson tree by adding at each level a cycle joining neighbour vertices. In particular, we will prove that, if
the underlying tree has no leaf, the simple random walk has almost sure positive speed.
