Per. with English. - M. : World, 1999. - 624 s. , il. A book by an American specialist containing a systematic presentation of one of the most relevant areas of modern theoretical physics Superstring Theory Combines Quantum Gravity and Modern Calibration Theories of Elementary Particles Within the framework of this theory were solved, in particular, the famous problems of ultraviolet divergences in quantum field theory and microscopic explanation of the entropy of black holes. The book presents in an accessible form the basic information on quantum field theory and string theory, an introduction to field string theory and methods for constructing four-dimensional strings. The book is equipped with an application that summarizes the theories of relativity, supersymmetry, gravity, provides information from group theory and differential geometry.
