Multimomentum Hamiltonian Formalism in Field Theory. Geometric Supplementary

Abstract

The well-known geometric approach to field theory is based on description of classical fields as sections of fibred manifolds, e.g. bundles with a structure group in gauge theory. In this approach, Lagrangian and Hamiltonian formalisms including the multiomentum Hamiltonian formalism are phrased in terms of jet manifolds. Then, configuration and phase spaces of fields are finite-dimensional. Though the jet manifolds have been widely used for theory of differential operators, the calculus of variations and differential geometry, this powerful mathematical methods remains almost unknown for physicists. This Supplementary to our previous article (hep-th/9403172) aims to summarize necessary requisites on jet manifolds and general connections.
