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

We review recent developments and results in testing general relativity (GR) at cosmological
scales. The subject has witnessed rapid growth during the last two decades with the aim of …

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 …

Over the past decade, f (R) theories have been extensively studied as one of the simplest
modifications to General Relativity. In this article we review various applications of f (R) …

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 …

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 …

The aim of this paper is to introduce a new modified gravity theory named f (G, T) f (G, T)
gravity (GG and T are the Gauss–Bonnet invariant and trace of the energy-momentum …

The theory of inflation with single and multiple fields is reviewed paying particular attention
to the dynamics of adiabatic and entropy/isocurvature perturbations which provide the …
