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

Abstract The Nobel Prize winning confirmation in 1998 of the accelerated expansion of our
Universe put into sharp focus the need of a consistent theoretical model to explain the origin …

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 …

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) …

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

Beyond Einstein's Gravity is a graduate level introduction to extended theories of gravity and
cosmology, including variational principles, the weak-field limit, gravitational waves …

We investigate the cosmological solutions of f (R, T) modified theories of gravity for a perfect
fluid in a spatially Friedmann-Lemaître-Robertson-Walker metric through the phase-space …

We investigate the cosmological behavior of mimetic F (R) gravity. This scenario is the F (R)
extension of usual mimetic gravity classes, which are based on re-parametrizations of the …

We study in detail the phase space of a Friedmann-Robertson-Walker universe filled with
various cosmological fluids that may or may not interact. We use various expressions for the …

We address the important issue of isotropisation of a pre-bounce contracting phase in f (R)
gravity, which would be relevant to constructing any viable nonsingular bouncing scenario in …
