Matrix exceptional Laguerre polynomials
Erik Koelink, Lucía Morey, Pablo Román
We give an analog of exceptional polynomials in the matrix valued setting by considering suitable factorizations of a given second order differential operator and performing Darbou…

Non Abelian Toda-type equations and matrix valued orthogonal polynomials
Alfredo Deaño, Lucía Morey, Pablo Román
In this paper, we study parameter deformations of matrix valued orthogonal polynomials (MVOPs). These deformations are built on the use of certain matrix valued operators which are…

Duality and difference operators for matrix valued discrete polynomials on the nonnegative integers
Bruno Eijsvoogel, Lucía Morey, Pablo Román
In this paper we introduce a notion of duality for matrix valued orthogonal polynomials with respect to a measure supported on the nonnegative integers. We show that the dual famil…
