Dark energy, inflation and dark matter from modified F(R) gravity
Shin'ichi Nojiri, Sergei D. Odintsov
We review modified gravity as realistic candidate to describe the observable universe expansion history. We show that recent cosmic acceleration, radiation/matter-dominated…
Phantom and non-phantom dark energy: The cosmological relevance of non-locally corrected gravity
S. Jhingan, S. Nojiri, S. D. Odintsov +3
In this paper we have investigated the cosmological dynamics of non-locally corrected gravity involving a function of the inverse d'Alembertian of the Ricci scalar, $f(\Box^{-1} R)…
The future evolution and finite-time singularities in -gravity unifying the inflation and cosmic acceleration
Shin'ichi Nojiri, Sergei D. Odintsov
We study the future evolution of quintessence/phantom dominated epoch in modified -gravity which unifies the early-time inflation with late-time acceleration and which is con…
Reconstructing the universe history, from inflation to acceleration, with phantom and canonical scalar fields
Emilio Elizalde, Shin'ichi Nojiri, Sergei D. Odintsov +2
We consider the reconstruction technique in theories with a single or multiple (phantom and/or canonical) scalar fields. With the help of several examples, it is demonstrated expli…
Inflationary cosmology and the late-time accelerated expansion of the universe in non-minimal Yang-Mills- gravity and non-minimal vector- gravity
Kazuharu Bamba, Shin'ichi Nojiri, Sergei D. Odintsov
We study inflationary cosmology and the late-time accelerated expansion of the universe in non-minimal Yang-Mills (YM) theory, in which the YM field couples to a function of the sc…
Can F(R)-gravity be a viable model: the universal unification scenario for inflation, dark energy and dark matter
Shin'ichi Nojiri, Sergei D. Odintsov
We review on the viability of -gravity. We show that recent cosmic acceleration, radiation/matter-dominated epoch and inflation could be realized in the framework of -g…
