A combinatorial approach to the CUE joint moment problem
George Snape
(University of Bristol)
Abstract
The joint moment problem asks to compute the averages of characteristic polynomials and their derivatives of random matrices drawn from one of the classical compact groups. Following the work of Bump and Gamburd (2006) and then Dehaye (2010), we will discuss the role of representation theory in this problem.
We then present recent work of the speaker giving an exact expression for these moments, valid for both finite matrix size and asymptotically. The expressions have a rich combinatorial structure, due to their relation to Kostka numbers and counting integer matrices (magic squares).
Time permitting, we will discuss a proof of a conjecture of Basor et al. (2018) on the connection between this problem and the irregular conformal block expansion of the Painlevé tau function.

Microsoft is making sign-in more secure by phasing out text and phone call authentication for multi-factor authentication (MFA). These methods are easier for attackers to compromise. Instead, users will be required to switch to stronger authentication methods such as a passkey, using the Microsoft Authenticator mobile app, or other more secure options.
Apparently there are about 7,000 people in the university whose only MFA methods are the ones that will be withdrawn. Are you one of the 7,000?
