Matrix Time-/Band- Limiting examples
Bruno Eijsvoogel
Time- and band-limiting in the context of orthogonal polynomials has been studied since the 1980's. It involves finding differential or difference operators with special commutativ…

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…

Ladder relations for a class of matrix valued orthogonal polynomials
Alfredo Deaño, Bruno Eijsvoogel, Pablo Román
Using the theory introduced by Casper and Yakimov, we investigate the structure of algebras of differential and difference operators acting on matrix valued orthogonal polynomials…
