Dirac’s Formalism for Time-Dependent Hamiltonian Systems in the Extended Phase Space
Dirac’s formalism for constrained systems is applied to the analysis of time-dependent Hamiltonians in the extended phase space. We show that the Lewis invariant is a reparametrization invariant, and we calculate the Feynman propagator using the extended phase space description. We show that the Fey...
