# Dirac string on (periodic) compact space

For a non-compact space, the Dirac string can be defined as a line joining the Dirac monopole to infinity (or another Dirac monopole). The region where the gauge connection is ill-defined. (as can be seen in Goddard and Olive's review)

But, for a (periodic) compact space, How could I define the Dirac string on this space, since there is no “infinity”?
