Cariñena, J. F.Gomis Torné, JoaquimIbort, L. A.Román-Roy, Narciso2012-04-262012-04-2619850022-2488https://hdl.handle.net/2445/24523We develop a theory of canonical transformations for presymplectic systems, reducing this concept to that of canonical transformations for regular coisotropic canonical systems. In this way we can also link these with the usual canonical transformations for the symplectic reduced phase space. Furthermore, the concept of a generating function arises in a natural way as well as that of gauge group.9 p.application/pdfeng(c) American Institute of Physics, 1985Sistemes hamiltoniansCamps vectorialsTeoria quànticaCamps de galga (Física)Hamiltonian systemsVector fieldsGeometryQuantum theoryGauge fields (Physics)info:eu-repo/semantics/article8221info:eu-repo/semantics/openAccess
