Quantum spherical functions of type $I ¨ $ as Macdonald-Koornwinder polynomials

Stein Meereboer

The theory of quantum symmetric pairs is applied to $q$ -special functions. Previous work shows the existence of a family $I ¨ $ -spherical functions indexed by the integers for each H…

Symmetries for spherical functions of type $I ¨ $ for quantum symmetric pairs

Stein Meereboer

Let $g$ be a complex semisimple Lie algebra and let $U_{q} (g)$ denote the associated Drinfel'd Jimbo quantized enveloping algebra. In this paper we stu…
