f (Q, T) gravity models with observational constraints
The paper presents late time cosmology in f (Q, T) gravity where the dark energy is purely
geometric in nature. We start by employing a well motivated f (Q, T) gravity model, f (Q, T)= m …

Inflation in f(R, T) gravity
The article presents modeling of inflationary scenarios for the first time in the f (R, T) theory of
gravity. We assume the f (R, T) functional form to be R+ η T R+ η T, where R denotes the …

Cosmographic analysis of a closed bouncing universe with the varying cosmological constant in f(R, T) gravity
Modelling of matter bounce in f (R, T) gravity has been presented with no violation of the null
energy condition. Only a closed universe with negative pressure is allowed in good …

Energy conditions in non‐minimally coupled f(R, T) gravity
In today's scenario, going beyond Einstein's theory of gravity leads us to some more
complete and modified gravity theories. One of them is the f (R, T) gravity in which R is the …
