Our approach is based on the dimensional reduction method for gauge and gravitational fields and relates symmetric solutions in EYMD theory to certain solutions of an effective dynamical system.\n  We interpret our solutions as cosmological solutions with an oscillating Yang-Mills field passing between topologically distinct vacua.
