Titre Resurgence and large genus asymptotics of intersection numbers
Horaire14:00 à 15:00

In this talk, I will present a new approach to the computation of the large genus asymptotics of intersection numbers of psi-classes, Theta-classes, and of r-spin intersection numbers. This technique is based on a resurgent analysis of the generating functions of such intersection numbers, which are computed via determinantal formulae, and relies heavily on the presence of an underlying first order differential system for each of the problems taken into consideration. With this approach we are able to extend the results of Aggarwal (2021) with the computation of subleading corrections, and to obtain completely new results on r-spin and Theta-class intersection numbers.
