摘要

通过对未截断的Bannai-Ito多项式和互补的Bannai-Ito多项式的非常规截断，得到了正交于Bannai-Ito双格(一致四格)上的新的双谱多项式。给出了所得到的拟bannai - ito多项式的完整表征，包括一个三项递推关系、一个dunkl -差分方程、一个超几何级数的显式表达式和一个正交关系。它们也被推导为$q$ $-para-Racah多项式的$q$ $到-1$ $的极限。建立了与偶$-1$ Hahn多项式的联系。

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, 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 $q\to -1$ limit of the $q$-para-Racah polynomials. A connection to the dual $-1$ Hahn polynomials is also established.
