Reviewing basic principles and exploring advanced topics and recent techniques, this modern treatment of quantum field theory is an ideal text for graduate students and an excellent reference for researchers. Key features include worked examples, applications, and end-of-chapter problems, with a solutions manual for instructors available online.

This collection of problems in Quantum Field Theory, accompanied by their complete solutions, aims to bridge the gap between learning the foundational principles and applying them practically. The carefully chosen problems cover a wide range of topics, starting from the foundations of Quantum Field Theory and the traditional methods in perturbation theory, such as LSZ reduction formulas, Feynman diagrams and renormalization. Separate chapters are devoted to functional methods (bosonic and fermionic path integrals; worldline formalism), to non-Abelian gauge theories (Yang-Mills theory, Quantum...
