Koornwinder’s polynomials and representations of the conformal group

Journal of Mathematical Physics, 1979
The tensor product of two massive, spinless, positive-energy ray representations of the conformal group of spacetime SO0(4,2)/Z2 is reduced in a momentum basis. The basis vectors for the irreducible subspaces (the ’’Clebsch–Gordan coefficients’’) are found to be intimately connected with Koornwinder’s polynomials in two dimensions.

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”.

Vanishing Integrals of Macdonald and Koornwinder polynomials

Transformation 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 ...

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.

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

Duke Mathematical Journal, 2001
The Koornwinder-Macdonald polynomials form a general class of orthogonal polynomials containing as limiting cases several important families of orthogonal polynomials, such as the Macdonald polynomials for classical root systems, the multivariable Wilson polynomials and Heckman-Opdam's Jacobi polynomials of \(BC_n\) type.

Generalized Gegenbauer Koornwinder’s type polynomials change of bases

AIP Conference Proceedings, 2017
In this paper we characterize the generalized Gegenbauer polynomials using Bernstein basis, and derive the matrix of transformation of the generalized Gegenbauer polynomial basis form into the Bernstein polynomial basis and vice versa.

A new property of a class of Koornwinder Laguerre polynomials

Integral Transforms and Special Functions, 2014
A new property of a class of Koornwinder's Laguerre polynomials is established. In this context, new classes of stable polynomials and polynomial pairs with real negative and interlacing roots are introduced. As a result, the distribution of zeros of a class of Mittag-Leffler functions is proved and new multiplier sequences are introduced.
