# Two-source dispersers for polylogarithmic entropy and improved Ramsey graphs II

 Computer Science/Discrete Mathematics Seminar II Topic: Two-source dispersers for polylogarithmic entropy and improved Ramsey graphs II Speaker: Gil Cohen Affiliation: California Institute of Technology Date: Tuesday, November 3 Time/Room: 10:30am - 12:30pm/S-101 Video Link: https://video.ias.edu/csdm/2015/1103-Cohen

In his 1947 paper that inaugurated the probabilistic method, Erdős proved the existence of $2 \log(n)$-Ramsey graphs on $n$ vertices. Matching Erdős' result with a constructive proof is a central problem in combinatorics that has gained a significant attention in the literature. In this talk we will present a recent work towards this goal (http://eccc.hpi-web.de/report/2015/095/).
