The simplest ΛCDM model provides a good fit to a large span of cosmological data but
harbors large areas of phenomenology and ignorance. With the improvement of the number …

Teleparallel gravity (TG) has significantly increased in popularity in recent decades, bringing
attention to Einstein's other theory of gravity. In this Review, we give a comprehensive …

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 …

Over recent decades, the role of torsion in gravity has been extensively investigated along
the main direction of bringing gravity closer to its gauge formulation and incorporating spin …

Teleparallel gravity and its popular generalization gravity can be formulated as fully invariant
(under both coordinate transformations and local Lorentz transformations) theories of …

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 f (Q) theories of modified gravity arise from the consideration of non-metricity as the
basic geometric quantity, and have been proven to be very efficient in describing the late …

We show that the well-known problem of frame dependence and violation of local Lorentz
invariance in the usual formulation of f (T) gravity is a consequence of neglecting the role of …
