Then we obtain the Murnaghan-Nakayama rule for the generalized functions. The rule are described explicitly in the cases of $K$-$k$-Schur functions and $k$-Schur functions, with concrete descriptions and algorithms for coefficients. Our work recovers the result of Bandlow, Schilling, and Zabrocki for $k$-Schur functions, and explains it as a degeneration of the rule for $K$-$k$-Schur functions. In particular, many other special cases promise to be detailed in the future.", "revisions": [ { "version": "v1", "updated": "2022-12-05T05:13:51.000Z" } ], "analyses": { "subjects": [ "05E05", "14N15" ], "keywords": [ "schur functions", "murnaghan-nakayama rule", "generalization", "special cases promise", "concrete descriptions" ], "note": { "typesetting": "TeX", "pages": 19, "language": "en", "license": "arXiv", "status": "editable" } } }
