We systematically review some standard issues and also the latest developments of
modified gravity in cosmology, emphasizing on inflation, bouncing cosmology and late-time …

In this review we present a thoroughly comprehensive survey of recent work on modified
theories of gravity and their cosmological consequences. Amongst other things, we cover …

The classical generalization of general relativity is considered as the gravitational alternative
for a unified description of the early-time inflation with late-time cosmic acceleration. The …

Extended Theories of Gravity can be considered as a new paradigm to cure shortcomings of
General Relativity at infrared and ultraviolet scales. They are an approach that, by …

We review in detail a number of approaches that have been adopted to try and explain the
remarkable observation of our accelerating universe. In particular we discuss the arguments …

Modified gravity theories have received increased attention lately due to combined
motivation coming from high-energy physics, cosmology, and astrophysics. Among …

After a decade and a half of research motivated by the accelerating universe, theory and
experiment have reached a certain level of maturity. The development of theoretical models …

We review various modified gravities considered as gravitational alternative for dark energy.
Specifically, we consider the versions of f (R), f (G) or f (R, G) gravity, model with non-linear …

We study a class of metric-variation f (R) models that accelerates the expansion without a
cosmological constant and satisfies both cosmological and solar-system tests in the small …

We suggest the modified gravity where some arbitrary function of Gauss–Bonnet (GB) term
is added to Einstein action as gravitational dark energy. It is shown that such theory may …
