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.
