摘要

In this paper, we have constructed the cosmological model of the universe in $f (R, T)$ theory of gravity in a Bianchi type VI$_h$ universe for the functional $f (R, T)$ in the form $f (R, T) = mu R + mu T$, where $R$ and $T$ are respectively Ricci scalar and trace of energy momentum tensor and $mu$ is a constant. We have made use of the hyperbolic scale factor to find the physical parameters and metric potentials defined in the space-time. The physical parameters are constrained from different representative values to build up a realistic cosmological model aligned with the observational behaviour. The state finder diagnostic pair is found to be in the acceptable range. The energy conditions of the model are also studied.
