Finite dimesional Hamiltonian formalism for gauge and field theories
We discuss in this paper the canonical structure of classical field theory in
finite dimensions within the {\it{pataplectic}} Hamiltonian formulation, where
we put forward the role of Legendre correspondance. We define the generalized
Poisson -brackets which are the analogues of the Poisson bracket
on forms. We formulate the equations of motion of forms in terms of
-brackets. As illustration of our formalism we present three
examples: the interacting scalar fields, conformal string theory and the
electromagnetic field.Comment: 52 pages. In this paper we give a more general hamiltonian
formulation for a gauge and field theories, it's an extension of our previous
paper math-ph/000402
