Abstract
A cosmological model that describes the evolution of n Einstein spaces (n > 1) in a theory with nonvanishing cosmological constant LAMBDA no t-equal 0 is considered. In the case in which all the spaces are Ricci flat, exact solutions of the Einstein and Wheeler-DeWitt equations ar e found. For LAMBDA < 0 solutions in the model that are interpreted as quantum wormholes are found. A generalization of the solutions in the case of a massless scalar field with minimal coupling is obtained.
