Introduction to the Theory of Quantized Fields
This monograph is an attempt to give a systematic presentation of the modern theory of quantized fields from its foundations right up to its most recent achievements.
In writing this book the authors were guided by their intention to present field theory from a unified point of view combining internal logical consistency and closure with completeness of the material covered. We also aimed, wherever possible, to introduce the maximum degree of clarity into the basic assumptions of the theory employed at the present stage of its development. At the same time, naturally, particular attention was devoted to the mathematical correctness of the arguments, as a result of which the extent of coverage of the applications of the theory to calculations of specific physical phenomena can be claimed to be only methodologically complete.
