In general there is no closed expression for them. We study some exceptional cases which can be factored into a product of a nice factor with a closed formula and an ugly factor with nice values for q=1 and q=-1. These can be interpreted as extensions of Gauss identity for alternating sums of q-binomial coefficients. In the course of this investigation we were led to many interesting conjectures. The most notable ones are explicit formulae for Hankel determinants of normalized Rogers-Szeg\\\"o polynomials.", "revisions": [ { "version": "v1", "updated": "2016-02-25T09:00:27.000Z" } ], "analyses": { "subjects": [ "05A30", "11B65", "33D45" ], "keywords": [ "elementary observations", "polynomials", "hankel determinants", "natural q-analogues", "explicit formulae" ], "note": { "typesetting": "TeX", "pages": 28, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2016arXiv160207850C" } } }
