Universidade Federal do Rio de Janeiro Instituto de Fisica, Cidade Universitaria 21944, Rio de Janeiro, RJ, Brasil aut Symplectic projector in constrained systems [Elektronische Daten] [P. Pitanga] Summary: In this work we develop a geometric formalism for constrained Hamiltonian systems. Using a symplectic projector, we show that the variables compatible with the constraints are written as functions of the arbitrary variables. Their Poisson bracket is just the Dirac bracket of the unconstrained variables. This approach yields in a natural way all properties associated to a generalized symplectic structure with a well-defined effective Hamiltonian.
