Algebraic Graph Theory-John Bamberg

Ramsey numbers and configurations of finite polar spaces

Abstract: This talk is on some joint work with Anurag Bishnoi and Ferdinand Ihringer, about a simple observation on how Ramsey theory relates to certain induced subgraphs of collinearity graphs arising from finite polar spaces; the natural geometries for the finite simple groups of classical Lie type

There will be a pre-seminar presenting relevant background at the beginning graduate level starting at 1pm
