摘要:
Let g(n) denote the least integer such that among any g(n) points in general position in the plane there are always n in convex position. In 1935, P. Erdos and G. Szekeres showed that g(n) exists and [GRAPHICS] Recently, the upper bounds has been slightly improved by Chung and Graham and by Kleitman and Pachter. In this paper we further improve the upper bound to [GRAPHICS]
