| Abstract: | 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 t the conclusion that if
q < 0 (deceleration parameter) then G, c are growing functions on time t while Λ is a negative decreasing function on time. |
