摘要

In this paper we study the evolution of a LRS Bianchi I Universe, filled with a bulk viscous cosmological fluid in the presence of time varying constants "but" taking into account the effects of a c-variable into the curvature tensor. We find that the only physical models are those which ``constants'' GG and cc are growing functions on time tt, while the cosmological constant Λ\Lambda is a negative decreasing function. In such solutions the energy density obeys the ultrastiff matter equation of state i.e. ω=1\omega=1.
