Relative asymptotics of multiple orthogonal polynomials for Nikishin systems of two measures
Abey López-García, Guillermo López Lagomasino
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…
On the convergence of multi-level Hermite-Padé approximants for a class of meromorphic functions
L. G. González Ricardo, G. López Lagomasino, S. Medina Peralta
The present paper deals with the convergence properties of multi-level Hermite-Padé approximants for a class of meromorphic functions given by rational perturbations with real coef…
Riemann-Hilbert analysis for a Nikishin system
Guillermo López Lagomasino, Walter Van Assche
In this paper we give the asymptotic behavior of type I multiple orthogonal polynomials for a Nikishin system of order two with two disjoint intervals. We use the Riemann-Hilbert p…
