Dynamics of an Anisotropic Universe in f(R,T)‎ Theory

Abstract EN

Dynamics of an anisotropic universe is studied in f(R,T) gravity using a rescaled functional f(R,T), where R is the Ricci Scalar and T is the trace of energy-momentum tensor.

Three models have been constructed assuming a power law expansion of the universe.

Physical features of the models are discussed.

The model parameters are constrained from a dimensional analysis.

It is found from the work that the anisotropic Bianchi type VIh (BVIh) model in the modified gravity generally favours a quintessence phase when the parameter h is either -1 or 0.

We may not get viable models in conformity with the present day observation for h=1.
