Time symmetric electrodynamics, electric charge conservation, and the Lorenz gauge

Abstract

We show how the Lorenz gauge condition is related to the electric charge conservation, in a universe where electrically charged point particles are created and annihilated. We derive our results using time symmetric electrodynamics, relying on observations made by Jacov Frenkel (in 1925) and John Archibald Wheeler (in 1940).Comment: 10 pages, 1 figure, more details in the conclusio
