Perturbative Quantum Electrodynamics and Axiomatic Field Theory

Focusing on relativistic quantum field theory, particularly quantum electrodynamics (QED), the book bridges the gap between mathematically rigorous and computationally effective approaches. It demonstrates how to derive perturbative QED rules from clear general assumptions without regularizations, addressing the infrared problem comprehensively. A unique local-observables method is introduced for describing particles and their interactions, leading to new expressions for observable-inclusive cross sections that differ from conventional methods, potentially sparking engaging discussions in the field.
