A topological mechanism of discretization for the electric charge

We present a topological mechanism of discretization, which gives for the fundamental electric charge the value q0=ℏc=5.29×10−19 C, about 3.3 times the electron charge. Its basis is the following recently proved property of the standard linear classical Maxwell equations: they can be obtained by change of variables from an underlying topological theory, using two complex scalar fields φ and θ the level curves of which coincide with the magnetic and the electric lines, respectively.
