which despite its simplicity involves some of the main difficulties of nonlinear elliptic Systems. The analysis of the existence, uniqueness, regularity and stability of its rotationally Symmetrie Solutions is not only instructive but also contributes to the general theory. For instance, it can be shown that the only known solution with singularities is unstable in dimension «, 3 ̂ «^6, but stable for n^l.
