Abstract:
If the first homotopy group of a spacetime manifold M is p cyclic with p≳1, we prove that there exists (p−1) nontrivial and nonequivalent fibre bundles on M with gauge group U(1) in which all the connections describe electromagnetic gauge fields without monopoles. Some spacetimes verifying this condition are introduced. This stresses the physical relevance of the difference between the first Chern classes with integer coefficients and those with real coefficients.
