quantum electrodynamics. In quasilinear approximation, the integral equation is solved by Mellin transformation, followed by the calculation of the Muskhelishvili index of the resultant singular integral operator.

Quantum electrodynamics is a time-symmetric theory that is part of the electroweak interaction, which is invariant under a generalized form of this symmetry, the PCT transformation. The thesis is defended that the arrow of time in electrodynamics is a consequence of the assumption of an initial state of high order, together with the quantum version of the equiprobability postulate.

In this article it is presented the idea that quantum electrodynamics has to be seen as a theoretical upgrade of classical electrodynamics and the theory of relativity, that permits an extension of classical theory in the description of phenomena, that while being clearly related to the conceptual framework of the classical theory – the description of matter, radiation, and their interaction – cannot be properly addressed from the classical theory. In this way quantum electrodynamics would not be a fundamental theory, (...) and principally, we could not consider classical electrodynamics as contained in the quantum theory and being recovered from it by some sort of limiting procedure.
