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

Following the recent theory of f (Q) gravity, we continue to investigate the possible existence
of wormhole geometries, where Q is the non-metricity scalar. Recently, the non-metricity …

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 …

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 …

The current interests in the universe motivate us to go beyond Einstein's General theory of
relativity. One of the interesting proposals comes from a new class of teleparallel gravity …

In this study, we found a new traversable wormhole solution in the framework of a
bumblebee gravity model. With these types of models, the Lorentz symmetry violation arises …

Mimetic gravity is a Weyl‐symmetric extension of General Relativity, related to the latter by a
singular disformal transformation, wherein the appearance of a dust‐like perfect fluid can …

In this work, we construct traversable wormhole geometries in the context of f (R) modified
theories of gravity. We impose that the matter threading the wormhole satisfies the energy …

The dark energy universe equation of state (EOS) with inhomogeneous, Hubble parameter
dependent term is considered. The motivation to introduce such a term comes from time …
