Branching Rules for Koornwinder Polynomials with One Column Diagrams and Matrix Inversions

Ayumu Hoshino, Jun'ichi Shiraishi

We present an explicit formula for the transition matrix $\mathcal{C}$ from the type $B{C}_n$ Koornwinder polynomials $P_{(1^r)}(x|a,b,c,d|q,t)$ with one column diagrams, to the type…
