A multi-orthogonal polynomials' approach to bulk queueing theory
Ulises Fidalgo
We consider a stationary Markov process that models certain queues with a bulk service of a fixed number of admitted customers. We find an integral expression of its transition…
Convergent non complete interpolatory quadrature rules
U. Fidalgo, J. Olson
We find a family of convergent schemes of nodes for non-complete interpolatory quadrature rules.
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…
Nikishin systems are perfect
U. Fidalgo Prieto, G. Lopez Lagomasino
K. Mahler introduced the concept of perfect systems in the general theory he developed for the simultaneous Hermite-Pade approximation of analytic functions. We prove that Nikishin…
Mixed type multiple orthogonal polynomials for two Nikishin systems
U. Fidalgo Prieto, A. López García, G. López Lagomasino +1
We study the logarithmic and ratio asymptotic of linear forms constructed from a Nikishin system which satisfy orthogonality conditions with respect to a system of measures generat…
