摘要:In this talk, I will first introduce some background on the problem of the joint moments of the derivatives of the characteristic polynomial of a Haar-distributed unitary matrix. Second, I will discuss the connections between these joint moments and integrable systems, specifically their connections to solutions of the σ-Painlevé V and σ-Painlevé III′ equations. Third, I will talk about applications of these results, including the rational structure in the large matrix size limit, explicit formulae for joint moments for finite matrix sizes, and an efficient method for computing joint moments of power-sum linear statistics of a certain determinantal point process.
