This means that one is always dealing with the Pfaff problem in those cases. In particular, knowing the degree of integrability of the 1-form is often essential, or, what amounts to the same thing, its canonical (i.e., normal) form. This paper consists of two parts: In the first part, the Pfaff problem is presented and discussed in a largely mathematical way, and in the second part, the mathematical generalities thus introduced are applied to various physical models in which the normal form of a 1-form has already been implicitly introduced, such as non-conservative forces, linear non-holonomic constraints, the theory of vortices and equilibrium thermodynamics. The role of integrability in the conservation of energy is a recurring theme.", "revisions": [ { "version": "v1", "updated": "2012-10-14T22:59:05.000Z", "comment": "56 pages, 3 tables", "journal": null, "doi": null }, { "version": "v2", "updated": "2017-03-16T13:42:30.000Z" } ], "analyses": { "keywords": [ "large class", "physical systems", "integrability", "pfaff problem", "linear non-holonomic constraints" ], "note": { "typesetting": "TeX", "pages": 56, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1191803, "adsabs": "2012arXiv1210.4976D" } } }
