Abstract

Properties of certain qq-orthogonal polynomials are connected to the qq-oscillator algebra. The Wall and qq-Laguerre polynomials are shown to arise as matrix elements of qq-exponentials of the generators in a representation of this algebra. A realization is presented where the continuous qq-Hermite polynomials form a basis of the representation space. Various identities are interpreted within this model. In particular, the connection formula between the continuous big qq-Hermite polynomials and the continuous qq-Hermite polynomials is thus obtained, and two generating functions for these last polynomials are algebraically derived.
