The representation theory for $sl_n$ has been one of the most important research areas for the past hundred years and within their the simple finite-dimensional modules have become very important. They are classified and Gelfand and Tsetlin actually gave an explicit construction of a basis for every simple module. We extend it by providing theorems and proofs, and construct monomial bases of the simple module.", "revisions": [ { "version": "v1", "updated": "2018-12-03T18:50:08.000Z" } ], "analyses": { "keywords": [ "simple module", "gelfand-tsetlin realisation", "construct monomial bases", "simple finite-dimensional modules", "famous simple lie algebra" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
