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…
Strong asymptotic of Cauchy biorthogonal polynomials and orthogonal polynomials with varying measure
L. G. González Ricardo, G. López Lagomasino
We give the strong asymptotic of Cauchy biorthogonal polynomials under the assumption that the defining measures are supported on non intersecting intervals of the real line and sa…
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…
