【Abstract】 Based on the canonical symmetries of constrained Hamiltonian systems, a counter-example to a conjecture of Dirac is given. Using the canonical first Noether theorem and canonical Noether identities, we have shown that Dirac’s conjecture fails in that example. There is no linearization of constraint in our treatment.更多还原
