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

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.
