TL;DR: Using ideas introduced by Wu and Yang in their recent nonsingular formulation of an action principle for classical Dirac magnetic monopoles, the authors modify Dirac's original formulation of the problem so as to avoid the difficulties encountered when charged-particle trajectories intersect singular strings.

TL;DR: In this paper, it was shown that in Dirac's formulation of the quantum-mechanical interaction of a magnetic monopole and an electric charge, the singular string attached to the monopole can be moved arbitrarily by an acceptable gauge transformation, and hence is not physically observable.
Abstract: It is shown that in Dirac's formulation of the quantum-mechanical interaction of a magnetic monopole and an electric charge the singular string he attached to the monopole can be moved arbitrarily by an acceptable gauge transformation, and hence is not physically observable, and that this formulation of the theory is equivalent to the recent formulation of Wu and Yang in which the use of potentials with strings is avoided.

TL;DR: In this paper, a method for constructing point-singular spherically symmetric monopoles in theories with an arbitrary compact simple gauge group was developed, where the monopole can be constructed by a simple group.
