This auxiliary space is a four-parameter generalization of the q-oscillator representations used previously. We derive generalized T-Q relations in which 3 of these parameters shift. After a suitable restriction of parameters, we give an explicit expression for the Q-operator of the 6-vertex model and show the connection with Baxter's expression for the central block of his corresponding operator.", "revisions": [ { "version": "v2", "updated": "2002-10-02T15:13:19.000Z" } ], "analyses": { "subjects": [ "82B23", "81R12", "81T40" ], "keywords": [ "vertex models", "generalized q-operator", "infinite-dimensional auxiliary space", "four-parameter generalization", "universal r-matrix" ], "tags": [ "journal article" ], "note": { "typesetting": "LaTeX", "pages": 22, "language": "en", "license": "arXiv", "status": "editable", "inspire": 606540 } } }
