“…Then restricting oneself to the class of random matrix measures invariant with respect to the change of basis (here the unitary invariant ensembles) the quantity of interest can be expressed as a determinant containing kernels made of polynomials orthogonal with respect to that measure [12]. In this way studying universality amounts mainly to investigating asymptotics of the orthogonal polynomials in various regimes, and is well established by now both on physical [13,14,15,16,17,18,19] as well as mathematical [20,21,22,23] level of rigor.…”
