FISI4430 Electrodinamica
The course will begin with a revision of ideas from electrodynamics involving potentials and fields. This involves the consideration of the scalar and vector potentials in electrodynamics, gauge transformations, conservation laws, etc. After recollecting the above which has been seen to some extent in earlier courses, the course goes over to relativistic electrodynamics. Here we shall start with special relativity and look into the covariant formulation of electrodynamics. In the last part of the course we will study retarded potentials and topics related to the radiation of moving charges and radiation in collisions.
