Stable exponential cosmological solutions with three factor spaces in (1 + 3 + 3 + k)-dimensional Einstein-Gauss-Bonnet model with a A-term
We consider a (7 + k)-dimensional Einstein-Gauss-Bonnet (EGB) model with the cosmological A-term. A cosmological model with three factor spaces of dimensions 3, 3 and k, k >2 is considered. Exact stable solutions with three (non-coinciding) Hubble-like parameters in these models are obtained. Some examples of solutions (e.g. with zero variation of the effective gravitational constant G) are considered in selected dimensions (for k = 5, 6). © 2019 World Scientific Publishing Company.
