On abelian solutions to the Yang-Mills-Higgs equations
The topology of some reducible connections in the (first) Georgi-Glashow model is considered. It is shown that pairs of U(1) connections with non- null Hopf index are minima of the Euclidean action under severe symmetry restrictions. Their physical meaning and some generalizations are outlined.
