We provide a combinatorial proof of this identity and an analytical proof of a more general identity for colored permutations. In addition, we prove some $q$-identities about the $q$-Stirling numbers of the second kind in types A, B and D.", "revisions": [ { "version": "v1", "updated": "2023-07-02T13:37:31.000Z" } ], "analyses": { "subjects": [ "05A05", "05A18", "05A19" ], "keywords": [ "second kind", "stirling numbers", "carlitzs major", "eulerian numbers", "combinatorial proof" ], "note": { "typesetting": "TeX", "pages": 24, "language": "en", "license": "arXiv", "status": "editable" } } }
