Universality Under Szegő’s Condition

Abstract

Abstract This paper presents a theoremon universality on orthogonal polynomials/randommatrices under a weak local condition on the weight function w. With a new inequality for polynomials and with the use of fast decreasing polynomials, it is shown that an approach of D. S. Lubinsky is applicable. The proof works at all points that are Lebesgue-points for both the weight function w and logw.
