We will discuss here some solutions of Yang-Mills field equations that recently have stirred interest because of their implications in elementary particle physics. We will start with the Landau-Ginzburg theory of superconductivity, in which a complex field 4(x) is introduced to represent the superfluid of condensed electrons (Cooper pairs). In the absence of explicit electromagnetic fields, the field 4 (x) can be assumed to be a constant throughout the medium, or a,+=O, but that is not a gauge-invariant concept. Rather, one should write
