Abstract

For sufficiently large nn, we show that in every configuration of nn points chosen inside the unit square there exists a triangle of area less than n8/71/2000n^{-8/7-1/2000}. This improves upon a result of Koml\'os, Pintz and Szemer\'edi from 1982. Our approach establishes new connections between the Heilbronn triangle problem and various themes in incidence geometry and projection theory which are closely related to the discretized sum-product phenomenon.
