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

Dynamics of an anisotropic universe is studied in $f(R,T)$ gravity using a rescaled functional $f(R,T)$. 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 $BVI_h$ model in the modified gravity can favour quintessence and phantom phase.Comment: 16 pages, 4 figure

Dynamical features of an anisotropic cosmological model

The dynamical features of Bianchi type $VI_h$ $(BVI_h)$ universe are investigated in $f(R,T)$ theory of gravity. The field equations and the physical properties of the model are derived considering a power law expansion of the universe. The effect of anisotropy on the dynamics of the universe as well on the energy conditions are studied. The assumed anisotropy of the model is found to have substantial effects on the energy condition and dynamical parameters.Comment: 11 pages, 7 figure
