Dark energy problem: from phantom theory to modified Gauss-Bonnet gravity
Shin'ichi Nojiri, Sergei D. Odintsov, O. G. Gorbunova
The solution of dark energy problem in the models without scalars is presented. It is shown that late-time accelerating cosmology may be generated by the ideal fluid with some impl…

Viscous FRW Cosmology in Modified Gravity
I. Brevik, O. Gorbunova, Y. A. Shaido
We discuss a modified form of gravity implying that the action contains a power αof the scalar curvature. Coupling with the cosmic fluid is assumed. As equation of state for the fl…

Dark Energy and Viscous Cosmology
I. Brevik, O. Gorbunova
Singularities in the dark energy universe are discussed, assuming that there is a bulk viscosity in the cosmic fluid. In particular, it is shown how the physically natural assumpti…
