- W2313179929 abstract "We consider a flat anisotropic metric in (4+1)and (5+1)-dimensional space-time in Gauss-Bonnet gravity. In the present presentation we are interesting in the behavior mostly in the vicinity of the cosmological singularity, which allows us to take into account only corrections of the highest possible order. In our case it is the GaussBonnet contribution, so we neglect Einstein terms. In the absence of matter sources this problem have been studied in Ref. 1,2, in the present presentation we take matter into account. The full Einstein Gauss-Bonnet system shows a complicated behavior even in the vacuum case and we leave investigation of such system with matter for a future work. We study a flat anisotripic Universe in a general case, i.e. we do not impose any relations between scale factors ai or Hubble parameters Hi = ȧi/ai. We use perfect fluid with the equation of state p = wρ as a matter source. To demonstrate the difference between (4+1) and (5+1) cases let us write down respective equation separately for these two cases. For (4+1) case we have" @default.
