چکیده
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 " G and c are growing functions on time t, while the cosmological constant Λ is a negative decreasing function. In such solutions the energy density obeys the ultrastiff matter equation of state i.e. ω = 1.

Causal Bulk Viscous LRS Bianchi I Models With Variable Gravitational and Cosmological “Constant”
In this paper we have investigated an LRS Bianchi I anisotropic cosmological model of the universe by taking time varying G and Λ in the presence of bulk viscous fluid source described by full causal non-equilibrium thermodynamics. We obtain a cosmological constant as a decreasing function of time and for m,n > 0, the value of cosmological “constant” for this model is found to be small and posi...

In the second self-creation theory of gravitation and in the general theory of relativity, Bianchi type VI0 cosmological model in the presence of viscous fluid is studied. An exact solution of the field equations is given by considering the cosmological model yields a constant decelerations parameter q=constant and the coefficients of the metric are taken as A(t)=[c1t+c<su...
متن کاملPerfect fluid LRS Bianchi I with time varying constants
It is investigated the behaviour of the “constants” G, c and Λ in the framework of a perfect fluid LRS Bianchi I cosmological model. It has been taken into account the effects of a c−variable into the curvature tensor. Two exact cosmological solutions are investigated, arriving to the conclusion that if q < 0 (deceleration parameter) then G, c are growing functions on time t while Λ is a negati...

An LRS Bianchi type-V cosmological models representing a viscous fluid distribution with a time dependent cosmological term Λ is investigated. To get a determinate solution, the viscosity coefficient of bulk viscous fluid is assumed to be a power function of mass density. It turns out that the cosmological term Λ(t) is a decreasing function of time, which is consistent with recent observations ...
