1. Convergencia relativa de polinomios ortogonales variantes

Abstract

12 pages, no figures.-- MSC2000 codes: Primary: 42C05, 30E15; Secondary: 30E10. We consider the relative asymptotic behaviour of orthogonal polynomials with respect to varying measures supported on the real line and the unit circle. The main feature of the results is the generality of the class of measures studied. El trabajo de los dos autores ha sido parcialmente financiado por la Dirección General de Investigación, Ministerio de Ciencia y Tecnología, a través del proyecto BFM2000-0206-C04-01 y además, en el caso de G. López, por el INTAS. Publicado

Abstract

OrthoQuad 2014 was an international symposium on orthogonality, quadrature, and related topics, held on January 20–24, 2014 in Puerto de la Cruz, Tenerife, Spain. It was held in memory of Professor Pablo González-Vera (1955–2012). [ABSTRACT FROM AUTHOR]

3. Nikishin systems on star-like sets: Ratio asymptotics of the associated multiple orthogonal polynomials, II.

Abstract

In this paper we continue the investigations initiated in López-García and López Lagomasino (2018) on ratio asymptotics of multiple orthogonal polynomials and functions of the second kind associated with Nikishin systems on star-like sets. We describe in detail the limiting functions found in López-García and López Lagomasino (2018), expressing them in terms of certain conformal mappings defined on a compact Riemann surface of genus zero. We also express the limiting values of the recurrence coefficients, which are shown to be strictly positive, in terms of certain values of the conformal mappings. As a consequence, the limits depend exclusively on the location of the intervals determined by the supports of the measures that generate the Nikishin system. [ABSTRACT FROM AUTHOR]
