Symplectic quantization and general constraint structure of a prototypical second-class system by Ignacio S. Gomez, Vipul Kumar Pandey, Ronaldo Thibes

“…Abstract We discuss a general prototypical constrained Hamiltonian system with a broad application in quantum field theory and similar contexts where dynamics is defined through a functional action obeying a stationarity principle. The prototypical model amounts to a Dirac–Bergmann singular system, whose constraints restrict the actual dynamics to occur within a differential submanifold, as is the case in the major part of field theoretical models with gauge symmetry. …”
