The $q$-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 $q$-difference operators is investigated.", "revisions": [ { "version": "v1", "updated": "2022-10-27T08:30:33.000Z" } ], "analyses": { "subjects": [ "33D45", "47B36" ], "keywords": [ "pastro polynomials", "real line", "algebraic treatment", "difference operators", "discrete biorthogonality relation" ], "note": { "typesetting": "TeX", "pages": 14, "language": "en", "license": "arXiv", "status": "editable" } } }
