Koornwinder’s polynomials and representations of the conformal group
Journal of Mathematical Physics, 1979The 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.

Generalized Gegenbauer Koornwinder’s type polynomials change of bases
AIP Conference Proceedings, 2017In 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.

Cubature formula for bivariate generalized Chebyshev Koornwinder’s type polynomials
AIP Conference Proceedings, 2018We formulate an explicit form of degree-ordered system of bivariate generalized Chebyshev Koornwinder’s type polynomials Un,r,d(γ,Μ,Ν)(u,v,w), γ > −1 in Bezer form over a triangular domain T. These polynomials form an orthogonal system with respect to the generalized measure 2π1-x2+Μδ−1+Nδ1 where M, N ≥ 0 and δx is a singular Dirac measure.

We study Macdonald–Koornwinder polynomials in the context of double affine Hecke algebras. Nonsymmetric Macdonald–Koornwinder polynomials are constructed by use of raising operators provided by a representation theory of the double affine Hecke algebra associated with A2l(2)-type affine root system.

A new property of a class of Koornwinder Laguerre polynomials
Integral Transforms and Special Functions, 2014A 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.
