In this note, we provide bijective proofs as well as refinements of those three theorems of Andrews. Our refinements take into account the numbers of parts in each of the two colors.", "revisions": [ { "version": "v1", "updated": "2022-02-06T09:32:58.000Z" } ], "analyses": { "subjects": [ "11P84", "05A17", "05A19" ], "keywords": [ "partition theorems", "combinatorial proofs", "refinements", "andrews revisited two-color partitions", "familiar kinds" ], "note": { "typesetting": "TeX", "pages": 11, "language": "en", "license": "arXiv", "status": "editable" } } }
