We extend this weight system to permutations and provide an efficient recursion for its computation. The construction for this weight system extends a similar construction for the universal polynomial weight system responsible for the Lie algebras $\\mathfrak{gl}(N)$ and superalgebras $\\mathfrak{gl}(N|M)$ introduced earlier by the second named author.", "revisions": [ { "version": "v1", "updated": "2024-11-18T13:04:50.000Z" } ], "analyses": { "keywords": [ "lie algebras", "universal polynomial weight system responsible", "universal weight system", "weight system extends", "second named author" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
