Abstract: A cosmological model describing the evolution of n Einstein spaces (n>1) with m- component perfect-fluid matter is considered. When all spaces are Ricci-flat and for any α-th component the pressures in all spaces are proportional to the density: [Formula: see text], the Einstein and Wheeler-DeWitt equations are integrated in the cases: (i) m=1, for all [Formula: see text]; (ii) m>1, for some special sets of [Formula: see text]. For m=1 the quantum wormhole solutions are also obtained.
