Dominici, D.Gomis Torné, Joaquim2012-04-262012-04-2619800022-2488https://hdl.handle.net/2445/24549In this work we develop the canonical formalism for constrained systems with a finite number of degrees of freedom by making use of the PoincarCartan integral invariant method. A set of variables suitable for the reduction to the physical ones can be obtained by means of a canonical transformation. From the invariance of the PoincarCartan integral under canonical transformations we get the form of the equations of motion for the physical variables of the system.7 p.application/pdfeng(c) American Institute of Physics, 1980Teoria quànticaDinàmicaEquacions en derivades parcialsQuantum theoryDynamicsPartial differential equationsinfo:eu-repo/semantics/article13798info:eu-repo/semantics/openAccess
