Abstract
In this article we consider the problems of the stability of spherically symmetric and axially symmetric constant chromomagnetic fields given by translationally invariant potentials that satisfy the Yang-Mills equation with nonzero current, where variations of the current are equal to zero. For an unstable mode of wave nature, the nonlinear terms of the Lagrangian are taken into account. It is shown that in this connection, the perturbation imposed on the background field is finite in time. Consequently, nonlinearity of the system leads to stabilization of the system as a whole.
