Abstract

We consider a (m+2)(m+2)-dimensional Einstein-Gauss-Bonnet model with the cosmological Λ\Lambda-term. We restrict the metrics to be diagonal ones and find for certain Λ=Λ(m)\Lambda = \Lambda(m) class of cosmological solutions with non-exponential time dependence of two scale factors of dimensions m>2m > 2 and 11. Any solutions from this class describes an accelerated expansion of mm-dimensional subspace and tends asymptotically to isotropic solution with exponental dependence of scale factors.
