The (almost) diagonal Ramsey numbers: Upper and lower bounds
Julian Sahasrabudhe, Professor, Department of Pure Mathematics and Mathematical Statistics (DPMMS), University of Cambridge,

In this second lecture, we will move on to discuss the recent improvement to the lower bounds for the diagonal Ramsey numbers. The classical argument of Erdos, gives a lower bound by colouring edges red/blue independently. In a recent breakthrough, this construction has been improved by considering a "random geometric graph".
