Abstract
Erdős and Szekeres proved in their 1935 paper that for every integer n ≥ 3 there exists a smallest positive integer N(n) such that any set of at least N(n) points in general position in the plane contains n points which are the vertices of a convex n-gon. They also posed the problem to determine the value of N(n) and conjectured that \(N(n) = 2^{n-2} + 1\) for all n ≥ 3. Despite the efforts of many mathematicians, the Erdős-Szekeres problem is still far from being solved. This chapter describes recent achievements towards the solution of this problem and some of its close relatives.
