Equivalence between the Lagrangian and Hamiltonian formalism for constrained systems
Carles Batlle, Joaquim Gomis, Josep Maria Pons, Narciso Román‐Roy · Journal of Mathematical Physics · 1986
The equivalence between the Lagrangian and Hamiltonian formalism is studied for constraint systems. A procedure to construct the Lagrangian constraints from the Hamiltonian constraints is given. Those Hamiltonian constraints that are first class with respect to the Hamiltonian constraints produce Lagrangian constraints that are FL-projectable.
