Vanishing Integrals of Macdonald and Koornwinder polynomials

open access: closedTransformation Groups, 2007
When one expands a Schur function in terms of the irreducible characters of the symplectic (or orthogonal) group, the coefficient of the trivial character is 0 unless the indexing partition has an appropriate form. A number of q,t-analogues of this fact were conjectured in [10]; the present paper proves most of those conjectures, as well as some new ...

A duality of MacDonald-Koornwinder polynomials and its application to integral representations

open access: closedDuke Mathematical Journal, 2001
We give a formula representing a duality of Macdonald-Koornwinder polynomials. Using this formula, an integral representation of Macdonald-Koornwinder polynomials is derived, a special case of which is the conjectural formula stated in [22]. We also present the corresponding formula to Heckman and Opdam's Jacobi polynomials of type $BC_m$.

Generalized Jacobi–Koornwinder’s-type Bernstein polynomials bases transformations

International Journal of Mathematics, 2016
This paper provides an explicit closed form of generalized Jacobi–Koornwinder’s polynomials of degree [Formula: see text] in terms of the Bernstein basis of fixed degree [Formula: see text] Moreover, explicit forms of generalized Jacobi–Koornwinder’s type and Bernstein polynomials bases transformations are considered.

Elliptic Analogues of the Macdonald and Koornwinder Polynomials

Proceedings of the International Congress of Mathematicians 2010 (ICM 2010), 2011
Perhaps the nicest multivariate orthogonal polynomials are the Macdonald and Koornwinder polynomials, respectively 2-parameter deformations of Schur functions and 6-parameter deformations of orthogonal and symplectic characters, satisfying a trio of nice properties known as the Macdonald “conjectures”.
