Dimensions of Cantor sets and Diophantine approximation

There are two recent cases where a specific knowledge of the dimension of certain Cantor set in the unit interval has had applications to problems in the Diophantine approximation. The first is on estimates by Matheus and Moriera on the size of the difference between the Lagrange and Markoff spectra, and the second is on the work of Bourgain-Kontorovich and Huang on the Zaremba conjecture. We will talk about these problems and, in particular, about the progress that has been made in estimating the dimension of such dynamically defined Cantor sets.

Why Euclidean domains are both easier and harder than you think

We give a gentle introduction to the proof that there is a Euclidean domain with no multiplicative norm.

Bipartite Turan problem

What is the largest graph not containing a copy of a fixed graph H? This question of Turan from 1941 remains open. The most challenging case is when H is bipartite. This case leads to interesting graph embedding problems on one hand, and mysterious algebro-geometric constructions on the other. In the talk, I will discuss the key problems and recent progress in the area.

On the geometry of invariant measures

In this talk I will try to explain that, in dynamical systems with some hyperbolicity, some invariant measures present a very nice geometric structure. I also will explain how this geometric structures can be used to recover certain rigidity of the system in study. The goal is to show this approach through examples, so I plan to spend some time describing these examples, their relevant measures and geometry.

Probabilistic aspects of number theory

We describe how probabilistic tools and reasoning are used to study problems about gaps
between prime numbers in various sequences, for example the sequence of all primes, and the sequence of prime values of a polynomial. This is joint work with Ben Green, Sergei Konyagin, James Maynard, Carl Pomerance and Terence Tao.
