We give a simple bijective proof of the conjecture in its original and more general setting. To do this we reformulate the problem in terms of cylindrical lattice paths.", "revisions": [ { "version": "v2", "updated": "2005-09-30T00:30:05.000Z" } ], "analyses": { "subjects": [ "05A15", "05C38" ], "keywords": [ "cylindrical lattice paths", "conjecture", "loehr-warrington", "zero-sum words", "simple bijective proof" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2005math......9521S" } } }
