Infrared singularity in the electron propagator in quantum electrodynamics
Description
Infrared singularity in the electron propagator is studied by means of the perturbation calculation exploited by Grammer and Yennie. The result agrees with those derived by nonperturbative methods. The difference between our result and the so-called exponentiation law is discussed together with the Ward-Takahashi identity. (author)
