DYNAMICS OF BULK VISCOUS DOMAIN WALL IN f(R,T) GRAVITY
Main Article Content
Abstract
In the present study, we have explored the solution of homogeneous and isotropic Friedmann-Robertson-Walker (FRW) space time in the frame of gravity proposed by Harko et al. (2011). We have considered model of gravity and bulk viscous domain wall as an source of energy. By examining the barotropic equation of state and the rule of variation of parameter presented by Berman (1983), we have found the solution of the field equations with a proper choice of model. We have looked into the dynamical and cosmological aspects of the model. The currently described model accelerate for and expands at a decreasing rate. Which corresponded to recent observations of the Universe [1, 2]. According to our findings, density and bulk viscosity coefficient is decreasing function of cosmic time . Also, we have discussed dimensionless parameters like jerk (), snap () and lerk ().
