摘要：

The dark energy model with equation of state (EoS) parameter is derived for a non-static plane symmetric space-time filled with a perfect fluid source in the framework of f (R, T) gravity (Harko et al., arXiv: 1104.2669v2 [gr-qc], 2011). To obtain a determinate solution, a special form of deceleration parameter (DP) is used. We have assumed that the relation between metric potentials and the EoS parameter is proportional to the skewness parameter. It is observed that the EoS parameter, and the skewness parameter in the model turn out to be functions of cosmic time. Some physical and kinematical properties of the model are also discussed.
