Alexander Gorodnik: Arithmetic Geometry and Dynamical Systems

Alexander Gorodnik, University of Bristol

Time: Wed 2009-11-18 16.00


Location: Room 3721, department of mathematics, KTH, Lindstedtsvägen 25, 7th floor

A fundamental problem in arithmetic geometry is to describe the structure of the sets of integral/rational solutions of polynomial equations. In particular one is interested in the number of solutions, distribution of solutions, and Diophantine approximation by solutions. In this talk we explain how these questions can be approached using techniques from the theory of dynamical systems.

Coffee and tea is served at 3:30 in the lunch room.
