Classical electrodynamics
             Dimiter Trifonov
 

      Preface  (reduced translation)

This textbook is written on the base of lectures delivered by the author to the students majoring Physics, and Physics and Mathematics in the South West University "N. Rilski" and is oriented mainly as a textbook for those students. It could be useful also to students of other specialities, and to teachers (instructors) and researchers as a reference book.

The foundations of the classical theory of the electromagnetic field are treated resorting to the variational least action principle and the Poincaree-Einstein relativity principle (special relativity theory).   In the more detailed description of the field properties the more familiar 3-dimensional formulations are preferably used. Illustrative problems are provided in each chapter along with the development of the subject. At many places further reading texts are pointed out.  In a 30 pages Appendix the reader may find the basic notions and formulas of the vector and tensor analysis, linear functionals and variational calculus.

All formulas in the main text are written in Gauss system. In the Appendix a table of basic formulas in Gauss and in SI systems is provided.

The author thanks the referees prof. L.I. Pavlov and prof. H.D. Popov and the assoc. prof. S. Donev for careful reading of the manuscript and valuable remarks.
