Compact invariant sets of the static spherically symmetric Einstein-Yang-Mills equations

In this Letter we obtain results concerning compact invariant sets of the static spherically symmetric Einstein-Yang-Mills (EYM) equations with help of studies of its localization. Let a be a cosmological constant and s be another parameter entering into these equations which is used for considering the physical time as a temporal variable, with s = 1, while s = - 1 is used for considering the physical time as a spatial variable. We show that in case s = 1; a < 0 the location of any compact invariant set is described by some system of linear inequalities. Then we prove that in case s = 1; a > 0 the set of all compact invariant sets consists of two equilibrium points only. Further, we state that in cases s = - 1; a < 0 and s = - 1; a > 0 there are only two equilibrium points and there are no periodic orbits. In addition, we prove that in the last two cases there are neither homoclinic orbits nor heteroclinic orbits as well.
