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

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 propose an extension of the symmetric teleparallel gravity, in which the gravitational
action L is given by an arbitrary function f of the non-metricity Q and of the trace of the matter …

We consider f (R, T) modified theories of gravity, where the gravitational Lagrangian is given
by an arbitrary function of the Ricci scalar R and of the trace of the stress-energy tensor T …

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 generalize the f (R) type gravity models by assuming that the gravitational Lagrangian is
given by an arbitrary function of the Ricci scalar R and of the matter Lagrangian L m. We …

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 …

In this paper, we investigate a cosmological model based on viscous f (R, T) gravity as a
potential alternative to dark energy. This model incorporates bulk viscosity and is analyzed …

Recent cosmological observations have posed a challenge for traditional theories of gravity:
what is the force driving the accelerated expansion of the universe? What if dark energy or …
