We obtain residue formulae for $N$-point local fields in terms of derivatives of delta functions and Bell polynomials. We introduce the notion of the space of descendants of $N$-point local fields which includes normal ordered products and coefficients of operator product expansions. We show that examples of $N$-point local fields include the vertex operators generating the boson-fermion correspondences of type B, C and D-A. We apply the normal ordered products of these vertex operators to the setting of the representation theory of the double-infinite rank Lie algebras $b_{\\infty}, c_{\\infty}, d_{\\infty}$. Finally, we show that the field theory generated by $N$-point local fields and their descendants has a structure of a twisted vertex algebra.", "revisions": [ { "version": "v1", "updated": "2013-07-18T04:47:30.000Z" } ], "analyses": { "keywords": [ "normal ordered products", "operator product expansions", "twisted vertex algebra", "point local fields", "vertex operators" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1243476, "adsabs": "2013arXiv1307.4830A" } } }
