Mathematics Subject Classification 2010Primary: Quantum Theory. Research exposition (monographs, survey articles) pertaining to quantum theory 81-02 • Quantum Theory. Other elementary particle theory in quantum theory 81V25 • Relativity and gravitational theory 83A99Secondary: Quantum Theory. Electromagnetic interaction; quantum electrodynamics 81V10 • General mathematical topics and methods in quantum theory 81Q99The 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.In this third volume of three, quantum electrodynamics is formulated in the language of physical "dressed" particles. A theory where charged particles interact via instantaneous action-at-a-distance forces is constructed - without need for renormalization. This theory describes electromagnetic phenomena in terms of directly interacting charges, but in full accord with fundamental principles of relativity and causality.Contents • Three ways to look at QFT • Dressing • What are advantages of dressed Hamiltonian? • Coulomb potential and beyond • Decays • RQD in higher orders • Classical electrodynamics • Experimental support of RQD • Particles and relativity • Special theory of relativity • Unitary dressing transformation • Integral for decay law • Coulomb scattering integral in fourth order • Relativistic invariance of Coulomb-Darwin-Breit electrodynamics
