This proof extends to a principal specialization due to Fomin and Stanley. Such a proof has been sought for over 20 years. Our bijective tools also allow us to solve a problem posed by Fomin and Kirillov from 1997 using work of Wachs, Lenart, Serrano and Stump. These results extend earlier work by the third author on a Markov process for reduced words of the longest permutation.", "revisions": [ { "version": "v1", "updated": "2017-02-09T18:45:18.000Z" } ], "analyses": { "subjects": [ "05A19" ], "keywords": [ "macdonalds reduced word formula", "bijective proof", "results extend earlier work", "macdonalds reduced word identity", "longest permutation" ], "note": { "typesetting": "TeX", "pages": 39, "language": "en", "license": "arXiv", "status": "editable" } } }
