Title:Transfer operators, Dolgopyat operators, expander graphs, and applications
Seminar:Dynamical systems seminar
Speaker:Dale Winter, Brown University
Abstract:
Spectral bounds on transfer operators have consequences in many areas of mathematics, including dynamics, number theory, and lattice counting problems. Two of the standard tools for proving such spectral bounds are the Dolgopyat operator technique and the expander graph approach of Bourgain-Gamburd-Sarnak. By combining these techniques we can obtain stronger spectral data and correspondingly stronger consequences. I’ll outline some examples of this approach and some of the corresponding applications in number theory and dynamics.
