The operators are simultaneously diagonalized by recently discovered q-polynomials (viz. Koornwinder's multivariable generalization of the Askey-Wilson polynomials). From the viewpoint of physics the algebra can be interpreted as consisting of the quantum integrals of a novel difference-type integrable sytem. This system generalizes the Calogero-Moser systems associated with non-exceptional root systems.24 pp. (printing format: landscape), Latex (+ amssymbols.sty)Functional AnalysisHigh Energy Physics - TheoryOperator AlgebrasExactly Solvable and Integrable Systemstext
