Abstract
We examine a “scale invariant” action of scalars and metric fields to which a matter term is added. We restrict our attention to the most symmetric solutions with the structure M 4xS 2. We present a cosmological solution in which we assume that in the primeval epoch the universe is radiation-dominated. The symmetry breaking pattern SU(3)→SU(2)xU(1) can be interesting for cosmology, on the contrary, the pattern SU(3)→SO(3) cannot.
