Stable exponential cosmological solutions with zero variation of G and three different Hubble-like parameters in the Einstein–Gauss–Bonnet model with a \(\Lambda \) -term

We consider a D-dimensional gravitational model with a Gauss–Bonnet term and the cosmological term \(\Lambda \). We restrict the metrics to diagonal cosmological ones and find for certain \(\Lambda \) a class of solutions with exponential time dependence of three scale factors, governed by three non-coinciding Hubble-like parameters \(H >0\), \(h_1\) and \(h_2\), corresponding to ...

Stable exponential cosmological solutions with zero variation of G in the Einstein–Gauss–Bonnet model with a \(\Lambda \) -term

A D-dimensional gravitational model with a Gauss–Bonnet term and the cosmological term \(\Lambda \) is considered. By assuming diagonal cosmological metrics, we find, for a certain fine-tuned \(\Lambda \), a class of solutions with exponential time dependence of two scale factors, governed by two Hubble-like parameters \(H >0\) and \(h 3\) and \(l > 1\), respectively, with \((m,l) ...
