Painlevé hierarchies in random matrix models

Abstract :
Unitary random matrix models are well-known for their many applications, as their eigenvalues model several systems such as log-gas, quantum chaos, and g-maps enumeration. Connections between the limiting eigenvalue distribution and special solutions of the Painlevé II and Painlevé V equations have been established for regular potentials. For non-regular potentials, such distribution is conjectured to be related to higher-order members of the Painlevé I and II hierarchies, while deformations of these models reveal connections with other integrable hierarchies. This is based on joint work with Mattia Cafasso and ongoing work in progress.

Painlevé Seminar Topics

Recently, we have encountered many interesting links between differential equations of Painlevé types and other fields of mathematics such as algebraic geometry, non-abelian Hodge theory and topological recursion and so on.
In this web seminar, we will organize research talks on Painlevé equations and related topics on web (zoom), basically about once every two or three weeks.
From September 2022, Regular time for seminar talk will be on Wednesday from 17:30--18:30 + discussion time in JST(Japan) or 10:30--11:30 in UTC+1. We are looking forward to your participation in the seminar. In order to get zoom access, please register through the form.
