Exact solutions in multidimensional cosmology with a term
A cosmological model that describes the evolution of \(n\) Einstein spaces \((n > 1)\) in a theory with nonvanishing cosmological constant \(\Lambda \neq 0\) is considered. In the case in which all the spaces are Ricci flat, exact solutions of the Einstein and Wheeler-De Witt equations are found. A generalization of the solutions in the case of a massless scalar field with minimal coupling is obtained.
