EXPANDING MODELS WITH A VARYING COSMOLOGICAL TERM AND BULK STRESS

摘要

The effect of a varying cosmological term and a dissipative bulk stress on the evolution of a homogeneous and isotropic universe is investigated. In the cases of interest neither analytical nor qualitative analysis is feasible and so we study these numerically only. Our work extends that of Calvao et al. to bulk stresses not considered in their analysis. [References: 21]
