# Dynamics Seminar: Asaf Katz (Chicago): "Quantitative disjointness of nilflows and horospherical flows."

2:15pm to 3:15pm

Ross 70

In his influential disjointness paper, H. Furstenberg proved that weakly-mixing systems are disjoint from irrational rotations (and in general, Kronecker systems), a result that inspired much of the modern

research in dynamics. Recently, A. Venkatesh managed to prove a quantitative version of this

disjointness theorem for the case of the horocyclic flow on a compact Riemann surface.
