The author’s procedure for passing from the Lagrangian to the Hamiltonian when the momenta are not independent functions of the velocities is put into a simpler and more practical form, the main results being obtained by a direct solution of the equations provided by the consistency requirements. It is shown how, under certain conditions, one can eliminate some of the degrees of freedom and so make a substantial simplification in the Hamiltonian formalism.

Constrained dynamics and exterior differential systems
TLDR
The Dirac analysis of constrained Hamiltonian mechanics is reformulated in the language of exterior differential systems, starting from the Lagrangian, moving through the generation of primary and secondary constraints and leading to the construction of symmetry generators for gauge symmetries.

Hamiltonian systems with constraints: a geometric approach
Hamilton-Dirac equations for a constrained Hamiltonian system are deduced from a variational principle. In the local problem for such systems an algorithm is proposed to obtain the final constraint…

The main goal of these lectures is to introduce and review the Hamiltonian formalism for classical constrained systems and in particular gauge theories. Emphasis is put on the relation between local…
Origin of the Lagrangian constraints and their relation with the Hamiltonian formulation
The theory of presymplectic systems is used for the study of mechanical systems described by singular Lagrangians in order to clarify the geometric meaning of the Euler–Lagrange equations for such…
