Stable exponential cosmological solutions with three factor spaces of dimensions m = 3, k1 = k and k2 = k in the Einstein–Gauss–Bonnet model with a Λ-term

Abstract

We consider a [Formula: see text]-dimensional Einstein–Gauss–Bonnet model with the cosmological [Formula: see text]-term. Exact stable solutions with three constant Hubble-like parameters in this model are obtained. In this case, the multidimensional cosmological model deals with three factor spaces: the external 3-dimensional “our” world and internal subspaces with dimensions [Formula: see text] and [Formula: see text].
