Query: A class of matrix-valued polynomials generalizing Jacobi Polynomials   A hierarchy of matrix-valued polynomials which generalize the Jacobi
polynomials is found. Defined by a Rodrigues formula, they are also products of
a sequence of differential operators. Each class of polynomials is complete,
satisfies a two-step recurrence relation, integral inter-relations, and
quasi-orthogonality relations.
