摘要:We consider local statistical properties of products of characteristic polynomials for the Hermite (Gaussian), Laguerre (Chiral), Jacobi and circular ensembles, and also for the shifted mean Gaussian ensemble. The expected products for the four classical ensembles are proven to have the same scaling limits in the bulk and at the edge of the spectrum. Furthermore, for the shifted mean Gaussian ensemble a phase transition phenomenon near the soft edge is found. All the asymptotic results rely on steepest descent method for integrals of Selberg type. This talk is based on joint works with P. Desrosiers.
