Fine structure of constraints in Hamiltonian formulation. (English) Zbl 1028.83011
Summary: We discuss constraint reorganization into first- and second-class, which is consistent with the Dirac procedure, i.e., which does not violate the division of the constraints according to their stages in the Dirac procedure. The possibility of such a reorganization is a crucial point in the study of relations between gauge symmetries in Lagrangian and Hamiltonian formulations.
