PPN limit and cosmological gravitational waves as tools to constrain f(R)-gravity
Mariafelicia De Laurentis, Salvatore Capozziello, Shin'ichi Nojiri +1
We discuss the PPN Solar-System constraints and the GW stochastic background considering some recently proposed gravity models which satisfy both cosmological and stability…
Vacuum energy fluctuations, the induced cosmological constant and cosmological reconstruction in non-minimal modified gravity models
G. Cognola, E. Elizalde, S. Nojiri +1
The one-loop effective action for non-minimal scalar modified gravity on de Sitter background with a constant scalar field is found. The corresponding induced cosmological constant…
Conformal Transformations in Cosmology of Modified Gravity: the Covariant Approach Perspective
Sante Carloni, Emilio Elizalde, Sergei Odintsov
The 1+3 covariant approach and the covariant gauge-invariant approach to perturbations are used to analyze in depth conformal transformations in cosmology. Such techniques allow us…
One-loop effective action for non-local modified Gauss-Bonnet gravity in de Sitter space
Guido Cognola, Emilio Elizalde, Shin'ichi Nojiri +2
We discuss the classical and quantum properties of non-local modified Gauss-Bonnet gravity in de Sitter space, using its equivalent representation via string-inspired local scalar-…
