Hamiltonian procedure of the Clairaut-type: analysis of constrained systems without constraints
Speaker:Steven Duplij (V.N. Karazin Kharkov National University, Ukraine and Mathematisches Institut, Uni Muenster, Deutschland)
Abstract:A self-consistent description of degenerate Lagrangian theories is made by introducing a Clairaut-type version of the Hamiltonian formalism. A generalization of the Legendre transform to the case when the Hessian is zero is done using the mixed (envelope/general) solutions of the multidimensional Clairaut equation. The corresponding system of equations of motion is equivalent to the Lagrange equations and has a subsytem for ``unresolved'' velocities. Then it is presented in the Hamiltonian-like form by introducing a new (non-Lie) bracket. This is a ``shortened'' formalism since finally it does not contain ``nondynamical'' (degenerate) momenta at all, and therefore there is no notion of constraint: nothing to constrain. Some examples are given. It is shown that any classical degenerate Lagrangian theory in its Clairaut-type Hamiltonian form is equivalent to the many-time classical dynamics.
