Its non-trivial reducible gauge symmetries and their algebra are defined in this very general setting by means of the inverse second Noether theorem. In contrast with gauge symmetries, non-trivial Noether and higher-stage Noether identities of Lagrangian theory can be intrinsically defined by constructing the exact Koszul-Tate complex. The inverse second Noether theorem that we prove associates to this complex the cochain sequence with the ascent operator whose components define non-trivial gauge and higher-stage gauge symmetries. These gauge symmetries are said to be algebraically closed if the ascent operator can be extended to a nilpotent operator. The necessary conditions for this extension are stated. The characteristic examples of Yang-Mills supergauge theory, topological Chern-Simons theory, gauge gravitation theory and topological BF theory are presented.", "revisions": [ { "version": "v2", "updated": "2008-11-25T08:20:45.000Z" } ], "analyses": { "subjects": [ "11.15.-q", "11.30.Na", "04.50.-h", "11.10.Ef" ], "keywords": [ "generic lagrangian field theory", "gauge symmetries", "inverse second noether theorem", "lagrangian theory", "ascent operator" ], "tags": [ "journal article" ], "publication": { "publisher": "AIP", "journal": "Journal of Mathematical Physics", "year": 2009, "month": "Jan", "volume": 50, "number": 1, "pages": 2903 }, "note": { "typesetting": "TeX", "pages": 27, "language": "en", "license": "arXiv", "status": "editable", "inspire": 791092, "adsabs": "2009JMP....50a2903G" } } }
