LRS Bianchi Type-V Cosmological Model for Barotropic Fluid Distribution with Bulk Viscosity & Decaying Vacuum Energy Λ(t) in Creation Field Theory of Gravitation

Abstract

LRS Bianchi type-V cosmological model in Hoyle Narlikar’s creation field theory of gravitation for barotropic fluid distribution with bulk viscosity in the presence of decaying vacuum energyΛ(t) has been studied. To get the deterministic solution, we have assumed Λ=1/(A²), where A is a scale factor (Chen &Wu; Phys. Rev. D, 41, 695, 1990). The physical aspects of the model are also discussed.
