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…

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…
