摘要
This article deals with the study of particle creation and bulk viscous stress for the hypersurface-homogeneous cosmological model in the context of general theory of relativity. Here, the solutions of the Einstein's field equations are reduced to a simple integration for arbitrary choice of the metric potential A(t). We have obtained the coefficient of bulk viscosity for truncated theory, full casual theory, and non-casual theory. A set of models have been taken into consideration based on the plausible relations among the variables. In addition, we have studied the physical and kinematical properties of the models.
