Partial results suggest that there are rich combinatorics to be found in these bases, including Eulerian numbers, Stirling numbers, quasi-Yamanouchi tableaux, and rook boards. These results also lead to further conjectures about the fundamental quasisymmetric expansions of these bases, which we prove for special cases.", "revisions": [ { "version": "v1", "updated": "2018-05-01T18:48:58.000Z" } ], "analyses": { "subjects": [ "05E05" ], "keywords": [ "schur expansion", "jack polynomials", "jack symmetric functions", "fundamental quasisymmetric expansions", "positivity conjectures" ], "tags": [ "conference paper" ], "note": { "typesetting": "TeX", "pages": 12, "language": "en", "license": "arXiv", "status": "editable" } } }
