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...
