Relative asymptotics of multiple orthogonal polynomials for Nikishin systems of two measures (2407.16738v2)
Published 23 Jul 2024 in math.CA
Abstract: We study the relative asymptotics of two sequences of multiple orthogonal polynomials corresponding to two Nikishin systems of measures on the real line, the second one of which is obtained from the first one perturbing the generating measures with non-negative integrable functions. Each Nikishin system consists of two measures.
