Stable exponential cosmological solutions with 3- and l-dimensional factor spaces in the Einstein–Gauss–Bonnet model with a $$\Lambda $$ Λ -term
Abstract A D-dimensional gravitational model with a Gauss–Bonnet term and the cosmological term $$\Lambda $$ Λ is studied. We assume the metrics to be diagonal cosmological ones. For certain fine-tuned $$\Lambda $$ Λ , we find a class of solutions with exponential time dependence of two scale factor...
