Specializing Koornwinder polynomials to Macdonald polynomials of type $B, C, D$ and $B C$

Kohei Yamaguchi, Shintarou Yanagida

We study the specializations of parameters in Koornwinder polynomials to obtain Macdonald polynomials associated to the subsystems of the affine root system of type $(C_n^\vee,C_n)…

A Littlewood-Richardson rule for Koornwinder polynomials

Kohei Yamaguchi

Koornwinder polynomials are $q$ -orthogonal polynomials equipped with extra five parameters and the $B C_{n}$ -type Weyl group symmetry, which were introduced by Koornwinder (1992) as…
