Multiple Orthogonal Polynomials on the Ball and Radial Extensions

Lidia FernÃ¡ndez, Juan Antonio Villegas

A primary method for constructing orthogonal polynomials on the unit ball consists of combining a Jacobi-type radial component with a spherical harmonic angular part. Building upon…

R $_{I I}$ type three term relations for bivariate polynomials orthogonal with respect to varying weights

Cleonice F. Bracciali, Antonia M. Delgado, Lidia FernÃ¡ndez +1

Given a bivariate weight function defined on the positive quadrant of $R^{2}$ , we study polynomials in two variables orthogonal with respect to varying measures obtained by…

Orthogonal Laurent polynomials of two real variables

RuymÃ¡n Cruz-Barroso, Lidia FernÃ¡ndez

In this paper we consider an appropriate ordering of the Laurent monomials $x^{i} y^{j}$ , $i, j \in Z$ that allows us to study sequences of orthogonal Laurent polynomials of…
