چکیده
We derive an elementary formula for Janossy densities for determinantal point processes with a finite rank projection-type kernel. In particular, for β = 2 polynomial ensembles of random matrices we show that the Janossy densities on an interval I ⊂ R can be expressed in terms of the Christoffel-Darboux kernel for the orthogonal polynomials on the complement of I.

A generalisation of the Faulhaber polynomials and Bernoulli numbers related to elliptic curves is introduced and investigated. This is applied to compute the density of states for the classical Lamé operators.
