On zero behavior of higher-order Sobolev-type discrete q-Hermite I orthogonal polynomials
Edmundo J. Huertas, Alberto Lastra, Anier Soria-Lorente +1
In this work, we investigate the sequence of monic q-Hermite I-Sobolev type orthogonal polynomials of higher-order, denoted as , which are orthog…
A dual watermaking scheme based on Sobolev type orthogonal moments for document authentication
Alicia María Centurión-Fajardo, Alberto Lastra, Anier Soria-Lorente
A dual watermarking scheme based on Sobolev type orthogonal moments, Charlier and Meixner, is proposed based on different discrete measures. The existing relation through the conne…
First order non-homogeneous q-difference equation for Stieltjes function characterizing q-orthogonal polynomials
J. Arvesú, A. Soria-Lorente
In this paper we give a characterization of some classical q-orthogonal polynomials in terms of a difference property of the associated Stieltjes function, i.e this function solves…
On new rational approximants to ζ(3)
J. Arvesú, A. Soria-Lorente
New (infinitely many) rational approximants to ζ(3) proving its irrationality are given. The recurrence relations for the numerator and denominator of these approximants as well as…
