Abstract

Description

Various models are under consideration with metric type flat FRW whose energy-momentum tensor is described by a perfect fluid whose generic equation state and taking into account the conservation principle, but considering some of the constants as variable. A set of solutions through dimensional analysis is trivially found. The numeric calculations carried out show that the results obtained are not discordant with those presently observed for cosmological parameters. However, the model seems irreconcilable with electromagnetic and quantum quantities. This makes us think that we are working with faulty hypothesis from the start
