- Abstract
- The present study deals with cosmological models of FRW universe in presence of bulk viscous fluid source in the scale-covariant theory of gravitation formulated by Canuto et al. [Phys. Rev. Lett. 39:429, 1977]. A new class of solutions for the modified Einstein’s field equations is obtained by considering time dependent deceleration parameter. It is observed that the models are accelerating at present epoch. Some physical aspects of the models are also discussed in this paper.
