Bispectrality and the ad conditions
F. Alberto Grunbaum
At the beginning of the study of the bispectral problem, see [18], the ad-conditions played a crucial role in finding non-classical instances. The connection with the ad-conditions…

Matrix valued orthogonal polynomials related to SU, their algebras of differential operators and the corresponding curves
F. Alberto Grünbaum, Manuel D. De la Iglesia
We give two examples of algebras of differential operators associated to families of matrix valued orthogonal polynomials arising from representations of SU. The first one g…

Random walks and orthogonal polynomials: some challenges
F. Alberto Grunbaum
The study of several naturally arising "nearest neighbours" random walks benefits from the study of the associated orthogonal polynomials and their orthogonality measure. I conside…
