Dans deux exemples concrets, je prouverai: le théorème de Szegö fort pour les matrices unitaires ; les moments du polynôme caractéristique de matrices de Ginibre.\\ |
| * 14h00-15h00: **[[http://google.com/search?q=Slim+Kammoun+math|Slim Kammoun]]** //Universality for random permutations.// It is known from the work of Baik, Deift and Johansson (1999) that we have the Tracy-Widom fluctuations for the longest increasing subsequence of uniform permutations. We prove that this result holds also in the case of the Ewens distribution and more generally for a class of random permutations with distribution invariant under conjugation. Moreover, we obtain the convergence of the first components of the associated Young tableaux to the Airy Ensemble as well as the global convergence to the Vershik-Kerov-Logan-Shepp shape. The talk will be boxed on the paper //Monotonous subsequences and the descent process of invariant random permutations//.\\ | * 14h00-15h00: **[[http://google.com/search?q=Slim+Kammoun+math|Slim Kammoun]]** //Universality for random permutations.// It is known from the work of Baik, Deift and Johansson (1999) that we have the Tracy-Widom fluctuations for the longest increasing subsequence of uniform permutations.
