Classic calibration fields. Part 1. Bosom theories. Rubakov V.A.

The basis of this book is the course of lectures, given to students of the 3rd and 4th courses of the Faculty of Physics of Moscow State University, specializing in the field of theoretical physics. The book consists of two parts. The first part contains the presentation of the main ideas of the theory of calibration fields, the construction of calibration-invariant lagranhyans and a description of the spectra of linear excitation, including over a non-trivial main state.

The second part of the book is devoted to the construction and interpretation of decisions, the existence of which is entirely due to non-linearity Field equations - solitons, “Euclidean bubbles”, instantons and sphalerons.

The material presented can be studied in parallel with the study of quantum mechanics, and then the quantum theory of the field. In this regard, the book should be useful to both scientists and graduate students and students of senior courses of universities.
