From Classical Field Theory to Perturbative Quantum Field Theory

A novel approach to perturbative quantum field theory is developed,which is conceptually clear,mathematically rigorous and pragmatically useful for physicists. It is based on deformation quantization of the underlying free theory and maintains as much of the classical structure as possible.

This groundbreaking book presents a novel and innovative approach to perturbative quantum field theory. It begins by formulating classical field theory in a perturbative manner, and then employs deformation quantization to achieve quantization. The key principle guiding this approach is to preserve as much of the classical structure as possible.

The resulting formulation of perturbative quantum field theory is a clear, rigorous, and practical tool for physicists. It is a version of the Epstein-Glaser renormalization that offers a conceptual understanding, mathematical precision, and practical utility. Furthermore, the book delves into the connection between traditional formulations of perturbative quantum field theory and elucidates the formalism through numerous examples and exercises.

By adopting this novel approach, physicists will gain a deeper insights into the complexities of quantum field theory and be able to apply its principles to solve a wide range of physical problems. This book is a valuable resource for advanced students, researchers, and practitioners in the field of quantum physics.
