Abstract
In this chapter a few essential facts of classical relativistic field theory are summarized. It will first be shown how to derive the equations of motion of a field theory, for example the Maxwell equations of electrodynamics, from a Lagrangian. Second, the connection between symmetries of the Lagrangian and conservation laws will be discussed1. This chapter follows very closely the presentation in [4] which can also serve as a more expanded, yet still quite easy to follow introduction to modern field theories of fundamental interactions.
