The Electrodynamics with Magnetic Monopoles. I The Electrodynamics with Magnetic Monopoles.

The present formulation is a refined version of the fiber bundle formulation of Wu and Yang with regard to the following. We use i) the Dirac strings as subsidiary variables and ii) a background vector potential to separate terms which depend kinematically on monopoles. As a result, our formulation is more tractable than the Wu-Yang original version.
