Gauss-Bonnet type coupling to the curvature is considered. Renormalization methods are generalized for such coupling and the N-dimensional space-time. Calculations of creation of entropy and visible matter of the Universe by the gravity of dark matter are made.LATEX, 21 pages, no figureGeneral Relativity and Quantum CosmologyHigh Energy Physics - Theorytext
