Relativistically covariant formulation of the canonical theory of classical fields I

Abstract

An explicit Lorentz covariant formulation of the canonical theory for classical fields is established on a space-like hypersurface. Hamilton's equations and a Poisson bracket are defined on the space-like hypersurface. The Poisson bracket relations between total momentum and total angular momentum satisfies the Poincar{é} algebra. It is shown that our Poisson bracket has the same symplectic structure that was brought in the covariant symplectic approach.
