Number theory

    Physics is never far from the properties of the number systems used to describe it. The structure factor of fractals at infinity depends on the Pisot-Vijaraghavan property, in which all high powers of an irrational number (such as the golden ratio) are close to integers. The escape from an open integrable billiard in the limit of small holes depends on the Riemann zeta function and more generally Dirichlet L-functions, which in turn are related to the distribution of prime numbers.
