Variational Methods in Field Theory the four-momentum and the four-dimensional angular momentum. At first sight these two aspects – relativistic invariance and the presence of conservation laws – do not seem to have anything to do with each other. . – which intertwines them in an inextricable way – relies, actually, heavily on a fund

Generation of Electromagnetic Fieldslectromagnetic waves. In this chapter we address another fundamental problem of classical electrodynamics: the determination of the electromagnetic field generated by an arbitrary distribution of moving charges, which amounts to solve Maxwell’s equations in the presence of a generic four-current ..

Electromagnetic Radiationmined the electromagnetic field generated by a particle in arbitrary motion – the Liénard-Wiechert field – realizing that, if the particle is accelerated, this field includes a ., which at large distances decreases as 1 / . and transports energy and momentum. In the second place, we found that the d

Gravitational Radiations, we will consider both radiations mainly in the non-relativistic limit, i.e. we shall assume that they are generated by objects moving with speeds much smaller than the speed of light. In this case the multipole approximation yields sensible, analytic, results, and so we will have at our disposal

Radiation in the Ultrarelativistic Limit gain such ultrarelativistic velocities, the energies of the particles must be increased far beyond their rest masses. In addition, if one wants to confine the particles in a bounded region, for instance, in an ., their trajectories must be bent. During both these processes the particles are subject
