On higher dimensional gravity: the Lagrangian, its dimensional reduction and a cosmological model
arXiv:2108.10633
Abstract
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.
