Workshop on Dynamics, Discrete Analysis and Multiplicative Number Theory

The Unipotent Mixing Conjecture

Abstract: Low-lying horocycles are known to equidistribute on the modular curve. Here we consider the joint distribution of two low-lying horocycles of different speeds in the product of two modular curves and show equidistribution under certain necessary diophantine conditions. The techniques involve a combination of multiplicative number theory and ergodic theory. This is joint work with Philippe Michel.
