Bispectrality for Matrix Laguerre-Sobolev polynomials
Francisco Marcellán, Ignacio Zurrián
In this contribution we deal with sequences of polynomials orthogonal with respect to a Sobolev type inner product. A banded symmetric operator is associated with such a sequence o…

Hypergeometric operators with diagonal eigenvalues
C. Calderón, Y. González, I. Pacharoni +2
In this work we classify all the order-two Hypergeometric operators , symmetric with respect to some irreducible matrix-weight such that $DP_n=P_n\left(\begin{sm…

The Algebra of Differential Operators for a Gegenbauer Weight Matrix
Ignacio Zurrián
In this paper we study in detail algebraic properties of the algebra of differential operators associated to a matrix weight of Gegenbauer type. We prove that two s…
