Title: The Corners Theorem for Quasirandom Groups
Speaker: Donald Robertson
Speaker Info: Ohio state Universtiy
Brief Description:
Special Note:

The corners theorem, proved by Ajtai and Szemeredi in 1974, states that for any prescribed density, any dense subset of a large enough n-by-n grid contains the vertices of a right triangle. In this talk I will describe recent joint work with V. Bergelson and P. Zorin-Kranich on a version of the corners theorem for quasirandom groups (finite groups without low-dimensional complex representations) via ergodic theory.
