The results include the general time-dependent anholonomic case, and further refinements for autonomous systems or forces derived from a potential are obtained. These extend classical results for Lagrangian and Hamiltonian systems. Several examples show the optimality of the assumptions as well as the applicability of the results, including an application to relativistic pp-waves.", "revisions": [ { "version": "v2", "updated": "2012-10-23T17:19:53.000Z" } ], "analyses": { "subjects": [ "34A26", "34C40", "37C60", "53D25", "70G45", "83C75" ], "keywords": [ "general force field", "completeness", "second order differential equation", "trajectories" ], "tags": [ "journal article" ], "publication": { "doi": "10.1007/s00205-012-0596-2", "journal": "Archive for Rational Mechanics and Analysis", "year": 2013, "month": "Apr", "volume": 208, "number": 1, "pages": 255 }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1087272, "adsabs": "2013ArRMA.208..255C" } } }
