A new proof of the Erdős-Szekeres convex k-gon result
This is a new, short proof of the following theorem: For any \(k\geq 3\), there is a least integer N such that any set of N points in the plane, no three of which are collinear, contains k points which are the vertices of a convex k-gon. An extension to n-dimensional point sets is indicated.
