Yuval Yifrach's Homepage
I am a postdoc at University of Zurich under the guidance of Prof. Alex Gorodnik
I am interested in manifestations of Ergodic Theory and Homogenous Dynamics in Number Theory. Here is my CV.
My research statement is available upon request.

Research Interests
My research field is Ergodic theory, dynamical systems and homogeneous dynamics with applications to number theory. I typically apply dynamical tools, often related to hyperbolic geometry to deduce results in Diophantine approximation and in algebraic number theory. Most of my works are related to number fields and to dynamical objects which arise from them. Often, there is a symbiosis between understanding properties of these number fields and properties of certain dynamical systems.
