چکیده
S-Heun operators on linear and $q$-linear grids are introduced. These special cases of Heun related to Sklyanin-like algebras. The Continuous Hahn Big $q$-Jacobi polynomials functions which these have natural actions. We show that the encompass both bispectral Kalnins Miller's structure operators. four realize limit trigonometric degeneration original Sklyanin algebra. Finite-dimensional representations algebras obtained from a truncation condition. corresponding representation bases finite families polynomials: para-Krawtchouk $q$-para-Krawtchouk ones. A algebraic interpretation had been missing is thus obtained. also recover attached problems as quadratic combinations

Autoimmunity against a Tissue Kallikrein in IQI/Jic Mice
We have recently characterized IQI/Jic mice as a model for Sjögren’s syndrome (SS), a chronic autoimmune disease in humans. In SS, local lymphocytic infiltrations into salivary and lacrimal glands frequently develop to the involvement of systemic exocrine and nonexocrine organs, and the mechanism for progression of this disease remains obscure. Herein, we report identification of an autoantigen...
متن کاملDegenerate Sklyanin Algebras
New trigonometric and rational solutions of the quantum Yang-Baxter equation (QYBE) are obtained by applying some singular gauge transformations to the known Belavin-Drinfeld elliptic R-matrix for sl(2,C). These solutions are shown to be related to the standard ones by the quasi-Hopf twist. We demonstrate that the quantum algebras arising from these new R-matrices can be obtained as special lim...
متن کاملNew Bounds for Hahn and Krawtchouk Polynomials
For the Hahn and Krawtchouk polynomials orthogonal on the set {0, . . . , N} new identities for the sum of squares are derived which generalize the trigonometric identity for the Chebyshev polynomials of the first and second kind. These results are applied in order to obtain conditions (on the degree of the polynomials) such that the polynomials are bounded (on the interval [0, N ]) by their va...
متن کاملMore zeros of krawtchouk polynomials
Three theorems are given for the integral zeros of Krawtchouk polynomials. First, five new infinite families of integral zeros for the binary (q = 2) Krawtchouk polynomials are found. Next, a lower bound is given for the next integral zero for the degree four polynomial. Finally, three new infinite families in q are found for the degree three polynomials. The techniques used are from elementary...
متن کاملOn Krawtchouk polynomials
Krawtchouk polynomials play an important role in coding theory and are also useful in graph theory and number theory. Although the basic properties of these polynomials are known to some extent, there is, to my knowledge, no detailed development available. My aim in writing this article is to fill in this gap. Notation In the following we will use capital letters for (algebraic) polynomials, fo...
