Quantum field theory (QFT) provides the framework for many fundamental theories in modern physics, and over the last few years there has been growing interest i

The book is devoted to the subject of quantum field theory. It is divided into two volumes. The first volume can serve as a textbook on main techniques and resu

Despite its long history and stunning experimental successes, the mathematical foundation of perturbative quantum field theory is still a subject of ongoing res
