Finding the smallest integer N=ES_d(n) such that in every configuration of N points in R^d in general position there exist n points in convex position is one of the most classical problems in extremal combinatorics, known as the ErdÅ‘s-Szekeres problem.ÌýIn 1935, ErdÅ‘s and Szekeres famously conjectured that ES_2(n)=2^{n−2}+1Ìýholds, which was nearly settled by Suk in 2016, who showed that ES_2(n)≤2^{n+o(n)}. We discuss a recent proof that ES_d(n)=2^{o(n)}Ìýholds for all d≥3.
