Bannai-Ito polynomials and dressing chains    [PDF]

Maxim Derevyagin, Satoshi Tsujimoto, Luc Vinet, Alexei Zhedanov
Schur-Delsarte-Genin (SDG) maps and Bannai-Ito polynomials are studied. SDG maps are related to dressing chains determined by quadratic algebras. The Bannai-Ito polynomials and their kernel polynomials -- the complementary Bannai-Ito polynomials -- are shown to arise in the framework of the SDG maps.
