Our result generalizes the neutral-fermionic presentation of the Schur $P$- and $Q$-functions. As a corollary, we derive a generating function of the dual $K$-theoretic $Q$-function $gq_\\lambda$, which was conjectured by Nakagawa-Naruse. We also present a generating function of the dual $K$-theoretic $P$-function $gp_\\lambda$.", "revisions": [ { "version": "v1", "updated": "2023-01-30T09:14:23.000Z" } ], "analyses": { "subjects": [ "05E05", "05E14", "13M10", "14N15" ], "keywords": [ "generating function", "boson-fermion correspondence", "neutral-fermionic presentation", "result generalizes" ], "note": { "typesetting": "TeX", "pages": 18, "language": "en", "license": "arXiv", "status": "editable" } } }
