Gauss-Bonnet dark energy by Lagrange multipliers

Salvatore Capozziello, Andrey N. Makarenko, Sergei D. Odintsov

A string-inspired effective theory of gravity, containing Gauss-Bonnet invariant interacting with a scalar field, is considered in view of obtaining cosmological dark energy soluti…

Quasi-Rip universe induced by the fluid with inhomogeneous equation of state

I. Brevik, V. Obukhov, A. Timoshkin

We investigate a specific model for dark energy, which lead to the Quasi-Rip cosmology. In the Quasi-Rip model, the equation of the state parameter is less than -1 in the first…
