Using an asymptotic mapping, we relate them to the partition function of the directed polymer model on the square lattice. For a specific choice of the edge weight distribution, we obtain a model known as the log-Gamma polymer, which is integrable. Recent results about the fluctuations of free energy for the log-Gamma polymer allow us to prove Tracy-Widom type fluctuations for the smallest eigenvalue of the random Schroedinger operator. Joint with Balint Virag.\\ |

This is joint work with Valentin Féray.\\ | * 15h30-16h30: **[[http://igor-kortchemski.perso.math.cnrs.fr/|Igor Kortchemski]]** //The geometry of random minimal factorizations of a long cycle//\\ Résumé : We will be interested in the structure of random typical minimal factorizations of the n-cycle into transpositions, which are factorizations of (1,...,n) as a product of n-1 transpositions.
