Monomial and Rodrigues orthogonal polynomials on the cone

Rabia Aktas, Amilcar Branquinho, Ana Foulquie-Moreno +1

We study two families of orthogonal polynomials with respect to the weight function $w (t) (t^{2} - ∥ x ∥^{2})^{μ - \frac{1}{2}}$ , $μ > - \frac{1}{2}$ , on the cone $\{(x,t): \|x\| \le t, \, x \in \ma…

Oscillatory banded Hessenberg matrices, multiple orthogonal polynomials and random walks

Amilcar Branquinho, Ana Foulquié-Moreno, Manuel Mañas

A spectral Favard theorem for bounded banded lower Hessenberg matrices that admit a positive bidiagonal factorization is found. The large knowledge on the spectral and factorizatio…

Quadratic decomposition of bivariate orthogonal polynomials

Amílcar Branquinho, Ana Foulquié Moreno, Teresa E. Pérez

We describe bivariate polynomial sequences orthogonal to a symmetric weight function in terms of several bivariate polynomial sequences orthogonal with respect to Christoffel trans…
