Hydrostatic equilibrium and stellar structure in f(R)-gravity
S. Capozziello, M. De Laurentis, S. D. Odintsov +1
We investigate the hydrostatic equilibrium of stellar structure by taking into account the modi- fied Laé-Emden equation coming out from f(R)-gravity. Such an equation is obtained…
U(1) Invariant F(R) Horava-Lifshitz Gravity
Josef Kluson, Shin'ichi Nojiri, Sergei D. Odintsov +1
This paper is devoted to the study of various aspects of projectable F(R) Horava-Lifshitz (HL) gravity. We show that some versions of F(R) HL gravity may have stable de Sitter solu…
Non-singular exponential gravity: a simple theory for early- and late-time accelerated expansion
E. Elizalde, S. Nojiri, S. D. Odintsov +2
A theory of exponential modified gravity which explains both early-time inflation and late-time acceleration, in a unified way, is proposed. The theory successfully passes the loca…
On Isotropic Turbulence in the Dark Fluid Universe
Iver Brevik, Olesya Gorbunova, Shin'ichi Nojiri +1
As first part of this work, experimental information about the decay of isotropic turbulence in ordinary hydrodynamics, u^2(t) proportional to t^{-6/5}, is used as input in FRW equ…
Unified cosmic history in modified gravity: from F(R) theory to Lorentz non-invariant models
Shin'ichi Nojiri, Sergei D. Odintsov
Classical generalization of general relativity is considered as gravitational alternative for unified description of the early-time inflation with late-time cosmic acceleration. Th…
Screening of cosmological constant in non-local gravity
Shin'ichi Nojiri, Sergei D. Odintsov, Misao Sasaki +1
We discuss a possible mechanism to screen a cosmological constant in non-local gravity. We find that in a simple model of of non-local gravity with the Lagrangian of the form, $R+f…
