Perfect Fluid LRS Bianchi I with Time Varying Constants

Abstract

It is investigated the behaviour of the ``constants'' $G,$ $c$ and $\Lambda$ 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 $\Lambda$ is a negative decreasing function on time.
