This methodology enables us on the one hand to obtain enumerations connecting products of hook lengths and vectors of integers. This yields on the other hand a combinatorial interpretation of the Macdonald identities for affine root systems of the $7$ infinite families in terms of Schur functions, symplectic and special orthogonal Schur functions. From these results, we are able to derive $q$-Nekrasov--Okounkov formulas associated to each type. The latter for limit cases of $q$ yield Nekrasov--Okounkov type formulas corresponding to all the specializations given by Macdonald.", "revisions": [ { "version": "v1", "updated": "2023-06-13T18:36:44.000Z" } ], "analyses": { "subjects": [ "05E10", "05A15", "05A17" ], "keywords": [ "affine root systems", "macdonald identities", "combinatorial interpretation", "special orthogonal schur functions", "yield nekrasov-okounkov type formulas corresponding" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
