Abstract

In this study, we have investigated homogeneous and anisotropic Marder space-time with bulk viscous string matter distribution in f (R,T) gravity. For this aim we have used the anisotropy feature (sigma(x)(x)/theta) of Marder space-time and a deceleration parameter in two different f (R,T) models. We have obtained bulk viscous matter distribution solutions in f (R,T) gravity. Finally, some kinematical and physical properties are discussed.
