General Relativity is a theory of gravity that describes some the effects with high accuracy, such as solar system tests, gravitational lensing, waves, black holes, deflection angle, etc [...]

We investigate modified theories of gravity in the context of teleparallel geometries with possible Gauss-Bonnet contributions. The possible coupling of gravity with the trace of the energy-momentum tensor is also taken into account. This is motivated by the various different theories formulated in the teleparallel approach and the metric approach without discussing the exact relationship betwe...

Scenario of a bouncing universe is one the most active area research to arrive at singularity free cosmological models. Different proposals have been suggested avoid so called ‘big bang’ through quantum aspect gravity which yet proper understanding. In this work, on contrary, we consider three different approaches, each goes beyond General Relativity but remain within domain classical scenario,...
