A simple proof of Koornwinder’s addition formula for the little 𝑞-Legendre polynomials [PDF]

open access: yesProceedings of the American Mathematical Society, 1989
Recently Koornwinder found an addition formula for the little q q -Legendre polynomials by using Masuda et al.’s result that they are related to the matrix elements of the irreducible unitary representation of the twisted SU(2) {\text {SU(2)}} quantum group.

Addition formulas for q-special functions

open access: yes, 1995
A general addition formula for a two-parameter family of Askey-Wilson polynomials is derived from the quantum $SU(2)$ group theoretic interpretation. This formula contains most of the previously known addition formulas for $q$-Legendre polynomials as ...

Change of basis for generalized Chebyshev Koornwinder's type polynomials of first kind

open access: yes, 2015
In this paper an explicit form of generalized Chebyshev Koornwinder's type polynomial of first kind in terms of the Bernstein basis of fixed degree $n$ is provided. Moreover, we investigate generalized Chebyshev Koornwinder's type polynomials of first kind and Bernstein polynomials change of bases.
