As these concepts are defined for all Lie types, it has been a long-standing problem to express them based on a generalization of charge. I present a method for addressing this problem in classical Lie types, based on the recent Ram-Yip formula for Macdonald polynomials and the quantum Bruhat order on the corresponding Weyl group. The details of the method are carried out in type A (where we recover the classical charge) and type C (where we define a new statistic).", "revisions": [ { "version": "v1", "updated": "2011-06-16T18:19:25.000Z" } ], "analyses": { "subjects": [ "05E05", "33D52", "20G42" ], "keywords": [ "macdonald polynomials", "charge statistic", "quantum bruhat order", "corresponding weyl group", "positive combinatorial formulas" ], "note": { "typesetting": "TeX", "pages": 32, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2011arXiv1106.3296L" } } }
