Quantum Field Theory I: Basics in Mathematics and Physics | 1:a upplagan

This is the first volume of a modern introduction to quantum field theory which addresses both mathematicians and physicists, at levels ranging from advanced undergraduate students to professional scientists. The book bridges the acknowledged gap between the different languages used by mathematicians and physicists. For students of mathematics the author shows that detailed knowledge of the physical background helps to motivate the mathematical subjects and to discover interesting interrelationships between quite different mathematical topics. For students of physics, fairly advanced mathematics is presented, which goes beyond the usual curriculum in physics. This book presents the state of the art of scientific realization of Einstein's dream of a constructing a grand unified theory for the four fundamental forces in the universe (gravitational, electromagnetic, strong, and weak interaction).
