Tel Aviv University
Dear all,
This week at the Horowitz seminar on Probability, Ergodic Theory and
Dynamical Systems at Tel Aviv University we are happy to have:
Speaker: Ron Rosenthal, The Hebrew University of Jerusalem
Title: Random walks, spectrum and homology of complexes
Date: Monday, November 26
Time: 14:30
Place: Schreiber 309
There are well known connections between the random walk on a graph,
and its topological and spectral properties. Here we define a
stochastic process on higher dimensional simplicial complexes, which
reflects their homological and spectral properties in a parallel way.
This leads to high dimensional analogues (not all of which hold!) of
classical theorems of Kesten, Alon-Boppana, and others. No previous
knowledge is assumed. Joint work with Ori Parzanchevski.
Best regards,
