PROPOSAL FOR AN INTERPRETATION OF THE
HERMITIAN THEORY OF RELATIVITY
S. ANTOCI
Abstract. The equilibrium conditions for charges and currents, ap
parent in exact solutions of the field equations, lead one to regard the
Hermitian theory of relativity as the theory of a field endowed with two
sources: electromagnetic and colour fourcurrents.
1. Introduction
The Hermitian theory of relativity dates back to 1925, when Einstein
proposed it as a unitary field theory of gravitation and electromagnetism
[1]. Only in 1945, after several attempts of a different kind, did Einstein re
turn [2] to the original idea, which he subsequently pursued, together with
his collaborators, in several works until his death in 1955. Difficulties were
soon encountered when trying to find exact solutions of the field equations,
which could allow for some glimpse into the physical content of the theory
[3], while approximate calculations led to disconcerting results for the mo
tion of charged particles [4]. Both Einstein [5] and Schršodinger [6] did not
believe that the evidence brought against the theory by the approximate
calculations could be considered really conclusive: to them, the problem of
