Rational Ruijsenaars-schneider Hierarchy and Bispectral Difference Operators
Abstract. We show that a monic polynomial in a discrete variable n, with coefficients depending on time variables t1, t2, . . . is a τ -function for the discrete Kadomtsev-Petviashvili hierarchy if and only if the motion of its zeros is governed by a hierarchy of Ruijsenaars-Schneider systems. These τ -functions were considered in [10], where it was proved that they parametrize rank one solutio...
متن کاملBispectral Commuting Difference Operators for Multivariable Askey-wilson Polynomials
We construct a commutative algebra Az , generated by d algebraically independent q-difference operators acting on variables z1, z2, . . . , zd, which is diagonalized by the multivariable Askey-Wilson polynomials Pn(z) considered by Gasper and Rahman [6]. Iterating Sears’ 4φ3 transformation formula, we show that the polynomials Pn(z) possess a certain duality between z and n. Analytic continuati...
متن کاملM-FUZZIFYING DERIVED OPERATORS AND DIFFERENCE DERIVED OPERATORS
This paper presents characterizations of M-fuzzifying matroids bymeans of two kinds of fuzzy operators, called M-fuzzifying derived operatorsand M-fuzzifying difference derived operators.
متن کاملSTUDYING THE BEHAVIOR OF SOLUTIONS OF A SECOND-ORDER RATIONAL DIFFERENCE EQUATION AND A RATIONAL SYSTEM
In this paper we investigate the behavior of solutions, stable and unstable of the solutions a second-order rational difference equation. Also we will discuss about the behavior of solutions a the rational system, we show these solutions may be stable or unstable.
