On the convergence of multi-level Hermite-Padé approximants
L. G. González Ricardo, G. López Lagomasino, S. Medina Peralta
In the present paper we prove a Stieltjes type theorem on the convergence of a sequence of rational functions associated with a mixed type Hermite-Padé approximation problem of a N…
Logarithmic asymptotic of multi-level Hermite-Padé polynomials
L. G. González Ricardo, G. López Lagomasino, S. Medina Peralta
We study the logarihtnmic asymptotic of multiple orthogonal polynomials arising in a mixed type Hermite-Padé approximation problem associated with the rational perturbation of a Ni…
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…
Mixed type Hermite-Padé approximation inspired by the Degasperis-Procesi equation
G. López Lagomasino, S. Medina Peralta, J. Szmigielski
In this work we present new results on the convergence of diagonal sequences of certain mixed type Hermite-Padé approximants of a Nikishin system. The study is motivated by a mixed…
On the convergence of type I Hermite-Padé approximants for a class of meromorphic functions
G. López Lagomasino, S. Medina Peralta
We study the convergence of type I Hermite-Padé approximation for a class of meromorphic functions obtained by adding a vector of rational functions with real coefficients to a Nik…
Hermite-Padé approximation for certain systems of meromorphic functions
U. Fidalgo Prieto, G. López Lagomasino, S. Medina Peralta
We study the convergence of sequences of type I and type II Hermite-Padé approximants for certain systems of meromorphic functions made up of rational modifications of Nikishin sys…
On the convergence of type I Hermite-Padé approximants
G. López Lagomasino, S. Medina Peralta
Padé approximation has two natural extensions to vector rational approximation through the so called type I and type II Hermite-Padé approximants. The convergence properties of typ…
