Singularities in any physical theory are either remarkable indicators of the unknown
underlying fundamental theory, or indicate a change in the description of the physical reality …

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

The objective of this paper is to unveil the evolving traversable wormhole solutions within
the perspective of modified f (R, G) gravity, where R is Ricci scalar and G is Gauss Bonnet …

We review different dark energy cosmologies. In particular, we present the Λ CDM
cosmology, Little Rip and Pseudo-Rip universes, the phantom and quintessence …

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) …

Neutron star models in perturbative f (R) gravity are considered with realistic equations of
state. In particular, we consider the FPS, SLy and other equations of state and a case of …

We review inflationary cosmology in modified gravity such as R 2 gravity with its extensions
in order to generalize the Starobinsky inflation model. In particular, we explore inflation …
