On the Erdős-Rogers function

Julian Sahasrabudhe
(University of Cambridge)
Abstract
In this talk I will discuss some recent progress on a natural relative of the classical Ramsey problem, introduced by Erdős and Rogers. What is the largest K_s-free subset that can be found in every K_{s+1}-free graph on n vertices?
This is based on joint work with Rob Morris and Jacques Verstraete.
