Matrix-valued orthogonal polynomials related to hexagon tilings
Alan Groot, Arno B. J. Kuijlaars
In this paper, we study a class of matrix-valued orthogonal polynomials (MVOPs) that are related to 2-periodic lozenge tilings of a hexagon. The general model depends on many param…

A vector equilibrium problem for symmetrically located point charges on a sphere
Juan G. Criado del Rey, Arno B. J. Kuijlaars
We study the equilibrium measure on the two dimensional sphere in the presence of an external field generated by r+1 equal point charges that are symmetrically located around the n…
