| Popis: | By dimensional reduction of the Lovelock Lagrangian, effective four-dimensional field equations and expressions for the cosmological and gravitational constants are obtained. A cosmological model is discussed with the n-torus as internal space. Comment: 11 pages, a typo in equation (3.17) of the original publication has been corrected |
