Original Kurzfassung:
This paper deals with the geometric analysis of the evolutionary and the polysymplectic
approach in first order Hamiltonian field theory. Based on a variational formulation in the Lagrangian picture, two possible counterparts
in a Hamiltonian formulation are discussed. The main difference between these two approaches
important for the application is beside a different bundle construction the different Legendre transform as well as the analysis of the conserved
quantities. Furthermore the role of the boundary conditions in the Lagrangian and in the Hamiltonian picture will be addressed.
These theoretical investigations will be completed by the analysis of
several examples including the wave equation, a beam equation and a special subclass of continuum mechanics in the presented framework.
