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…
Determining Singularities Using Row Sequences of Padé-orthogonal Approximants
N. Bosuwan, G. López Lagomasino, E. B. Saff
Starting from the orthogonal polynomial expansion of a function corresponding to a finite positive Borel measure with infinite compact support, we study the asymptotic behavior…
