The derivation of Maxwell's equations from the equations of the quantum theory
M Fahmy · Proceedings of the Physical Society · 1932
In a theory developed by Flint and Fisher the fundamental equations of the quantum theory are expressed in terms of a five-dimensional geometry based upon the use of two inter-related tensors A and B. In the present paper Maxwell's equations are derived from the five-dimensional equations previously proposed, and the tensors A and B are exhibited as geometrical quantities related to the electromagnetic potential.
