Abstract

In this paper, we use asymptotic estimates of the Christoffel functions associated with regular measures satisfying Szegő’s condition locally to extend a recent universality result by D.S. Lubinsky. As a consequence, we obtain under the same conditions an extension of a very precise zero-spacing result of Levin and Lubinsky.
