The deviation factor and divergences in quantum electrodynamics, concrete examples. (English) Zbl 1476.81147
Summary: We consider the divergences in quantum electrodynamics. Our approach is based on ideas from the theory of generalized wave operators. In particular, we use the concept of the deviation factor. The deviation factor characterizes the deviations of the initial and final waves from the free waves. The approach is demonstrated on important examples.
