Abstract

The properties of the Pastro polynomials on the real line are studied with the help of a triplet of qq-difference operators. The qq-difference equation and recurrence relation these polynomials obey are shown to arise as generalized eigenvalue problems involving the triplet of operators, with the Pastro polynomials as solutions. Moreover, a discrete biorthogonality relation on the real line for the Pastro polynomials is obtained and is then understood using adjoint operators. The algebra realized by the triplet of qq-difference operators is investigated.
