The De Gruyter Studies in Mathematical Physics are devoted to the publication of monographs and high-level texts in mathematical physics. They cover topics and methods in fields of current interest, with an emphasis on didactical presentation. The series will enable readers to understand, apply and develop further, with sufficient rigor, mathematical methods to given problems in physics. For this reason, works with a few authors are preferred over edited volumes. The works in this series are aimed at advanced students and researchers in mathematical and theoretical physics. They can also serve as secondary reading for lectures and seminars at advanced levels.Mathematics Subject Classification 2010Primary: Quantum Theory. Research exposition (monographs, survey articles) pertaining to quantum theory 81-02 • Quantum Theory. Electromagnetic interaction; quantum electrodynamics 81V10 • Perturbative methods of renormalization applied to problems in quantum field theory 81T15Secondary: Operator Theory. Scattering theory of linear operators 47A40 • Feynman diagrams 81T18This second volume of three on relativistic quantum theories of interacting charged particles discusses quantum theories of systems with variable numbers of particles. Basics of the Fock space and quantum electrodynamics are covered with an emphasis on renormalization. In contrast to the usual treatment of the topic, particles (rather than fields) are chosen as basic ingredients.Contents • Fock space • Scattering in Fock space • Quantum electrodynamics • Renormalization • Useful integrals • Quantum fields of fermions • Quantum field of photons • QED interaction in terms of particle operators • Relativistic invariance of QFT • Loop integrals in QED • Scattering matrix in V/c₂ approximation • Checks of physical dimensions
