Formulas for Koornwinder polynomials

Laura Colmenarejo, Lucas Gagnon, Arun Ram

This paper provides formulas for Koornwinder polynomials in analogy with the creation formula, the alcove walk formula and the non-attacking fillings formula for the type $G L_{n}$ Ma…

$c$ -functions and Koornwinder polynomials

Laura Colmenarejo, Arun Ram

This paper develops the theory of Macdonald-Koornwinder polynomials in parallel analogy with the work done for the $G L_{n}$ case in [CR22]. In the context of the type $C C_{n}$ affine r…
