Title: Fluctuations of eigenvalues of a polynomial on Haar unitary and finite rank matrices
Abstract:
In this talk, I will explain how to calculates the fluctuations of eigenvalues of polynomials on large Haar unitaries cut by finite rank deterministic matrices. When the eigenvalues are all simple, we can give a complete algorithm for computing the fluctuations.
