Para-Bannai-Ito Polynomials

New bispectral polynomials orthogonal on a Bannai-Ito bi-lattice (uniform quadri-lattice) are obtained from an unconventional truncation of the untruncated Bannai-Ito and complementary Bannai-Ito polynomials. A complete characterization of the resulting para-Bannai-Ito polynomials is provided, inclu...

Zusammenfassung:New bispectral polynomials orthogonal on a Bannai-Ito bi-lattice (uniform quadri-lattice) are obtained from an unconventional truncation of the untruncated Bannai-Ito and complementary Bannai-Ito polynomials. A complete characterization of the resulting para-Bannai-Ito polynomials is provided, including a three-term recurrence relation, a Dunkl-difference equation, an explicit expression in terms of hypergeometric series, and an orthogonality relation. They are also derived as a → −1 limit of the -para-Racah polynomials. A connection to the dual −1 Hahn polynomials is also established.
