Seminar:Dynamical systems seminar
Speaker:Jesse Peterson, Vanderbilt University
A character on a group G is a class function of positive type. We'll say that G is character rigid if every character is a sum of an almost periodic character and a Dirac function. Based on rigidity results of Margulis and Zimmer, Connes conjectured in the early 80's that irreducible lattices in higher rank groups are character rigid. I will discuss a partial solution to this conjecture, which is based on joint works with Andreas Thom and Darren Creutz, and I will also discuss the relation to Margulis' and Zimmer's work, as well as some consequence in ergodic theory.
