The Action Principles in Mechanics,We begin this chapter with the definition of the action functional as time integral over the Lagrangian . of a dynamical system:

The Action Principle in Classical Electrodynamics,The main purpose of this chapter is to consider the formulation of a relativistic point particle in classical electrodynamics from the viewpoint of Lagrangian mechanics. Here, the utility of Schwinger’s action principle is illustrated by employing three different kinds of action to derive the equations of motion and the associated surface terms.

Application of the Action Principles,We begin this chapter by deriving a few laws of nonconservation in mechanics. To this end we first consider the change of the action under rigid space translation .. = .. and .(..) = 0.
