DESCRIPTION:Given r and k let R_r(k) be the minimum n such that any\nr-col
 ouring of K_n contains a monochromatic K_k. In 1935 Erd\\H{o}s and\nSzeker
 es proved that R_r(k)\\leq r^{rk}. In this talk I will discuss a\ngeometri
 c approach to improve this upper bound.\nBased on joint work with Balliste
