Combin. 28(4) (2021), Paper No. 4.38] found a determinant formula for the number of configurations in a specific such model, and he conjectured a closed form product formula for the evaluation of this determinant. We prove this conjecture here. Moreover, we actually generalize this determinant evaluation to a one-parameter family of determinant evaluations, and we present many more determinant evaluations of similar type - some proved, some left open as conjectures.", "revisions": [ { "version": "v1", "updated": "2024-01-16T16:35:00.000Z" } ], "analyses": { "subjects": [ "15A15", "05A15", "05A19", "05B45", "82B20" ], "keywords": [ "determinant evaluation", "di francescos determinant", "twenty-vertex configurations", "closed form product formula", "vertex model" ], "tags": [ "journal article" ], "note": { "typesetting": "LaTeX", "pages": 37, "language": "en", "license": "arXiv", "status": "editable" } } }
