Recent Results on Ramsey Numbers
Ramsey
Theory is the study of inevitable structure, with examples occurring in various areas, including Graph Theory, Number Theory and Geometry. In this mini-course we discuss recent major advances, including the new lower bound on R(4, k) and the exponential improvement for the upper bound on diagonal Ramsey numbers.
