We show that this solves the Jacobi identity violation problem occuring in the Dirac quantization case and yields a well defined Fock space. By requiring the uniqueness of the ground state, we show that for non-constrained systems this approach gives the same results as Dirac quantization.LaTeX, 11 pagesHigh Energy Physics - Theorytext
