„Quantum theory and enumerative problems “
Gemeinsames Mathematik / Physik-Kolloquium
Prof. Marcos Marino, Université de Genève

In quantum theory we are very often interested in counting objects. For example, to understand perturbation theory in quantum physics, we have to count graphs by using combinatorial techniques, while in string theory we have to count curves in manifolds, by using algebraic geometry. In this talk I will explore some of these enumerative problems. I will start with some simple examples in quantum theory and in the theory of ordinary differential equations. I will then introduce more complicated counting problems in two a priori unrelated subjects: random matrix theory and in string theory. As I will show, these subjects are in fact deeply related and sometimes an enumerative problem in string theory can be formulated in the language of random matrices.
