Title: The Newhouse gap lemma and patterns in products of Cantor sets
Abstract: Many important problems throughout mathematics can be summarized as follows: how large must a set be in order to ensure that it exhibits some type of structure? A classic example of importance in geometric measure theory and harmonic analysis is the Falconer distance problem, which asks how large the Hausdorff dimension of a compact set must be to ensure it determines a positive measure worth of distances. More generally, one may ask for an abundance of more complicated point configurations. There has been considerable recent progress on variants of these problems where Hausdorff dimension is replaced by a quantity called thickness, which provides an alternative way to quantify the “size” of a compact set. In these talks, I will give an overview of thickness from the ground up, and discuss some applications to finding point configurations in Cantor sets.
