Orthogonal functions related to Lax pairs in Lie algebras

Journal article (2021) - W.G.M. Groenevelt (author) , Erik Koelink (author)

We study a Lax pair in a 2-parameter Lie algebra in various representations. The overlap coefficients of the eigenfunctions of L and the standard basis are given in terms of orthogonal polynomials and orthogonal functions. Eigenfunctions for the operator L for a Lax pair for sl(d ...
