Inflation in a conformally-invariant two-scalar-field theory with an extra term
Kazuharu Bamba, Sergei D. Odintsov, Petr V. Tretyakov
We explore inflationary cosmology in a theory where there are two scalar fields which non-minimally couple to the Ricci scalar and an additional term, which breaks the confor…
Reconstruction and deceleration-acceleration transitions in modified gravity
Shin'ichi Nojiri, Sergei D. Odintsov, Alexey Toporensky +1
We discuss the cosmological reconstruction in modified Gauss-Bonnet and F(R) gravities. Two alternative representations of the action (with and without auxiliary scalar) are consid…
A Note on the Viability of Gauss-Bonnet Cosmology
R. Chingangbam, M. Sami, P. V. Tretyakov +1
In this paper, we analyze the viability of a vacuum Gauss-Bonnet cosmology by examining the dynamics of the homogeneous and anisotropic background in 4+1 dimensions. The trajectori…
From inflation to dark energy in the non-minimal modified gravity
Shin'ichi Nojiri, Sergei D. Odintsov, Petr V. Tretyakov
We consider the modified gravity non-minimally coupled with matter Lagrangian for the description of early-time and late-time universe. Such () gravity in the absence…
Dark energy from modified F(R)-scalar-Gauss-Bonnet gravity
Shin'ichi Nojiri, Sergei D. Odintsov, Petr V. Tretyakov
The modified F(R)-scalar-Gauss-Bonnet gravity is proposed as dark energy model. The reconstruction program for such theory is developed. It is explicitly demonstrated that the know…
