Asymptotic distribution of zeros of polynomials satisfying difference equations
Abstract
We propose a way to find the asymptotic distribution of zeros of orthogonal polynomials pn(x) satisfying a difference equation of the form B(x)pn(x+δ)-C(x,n)pn(x)+D(x)pn(x-δ)=0. We calculate the asymptotic distribution of zeros and asymptotics of extreme zeros of the Meixner and Meixner-Pollaczek polynomials. The distribution of zeros of Meixner polynomials shows some delicate features. We indicate the relation of our approach to the WKB technique and to the approach based on the Nevai-Ullman distribution.
