The FRW Universes with Barotropic Fluids in Jordan-Brans-Dicke Theory 95 where, on this occasion and since without loosing any in generality one can put and give the scale factor in terms of “cosmic time 3. RADIATION Radiation or ultrarelativistic fluids where imply Such fluids cannot generate a scalar field that if present must then be sourceless Here, plays the role of dependent variable on defined by With them one obtains the following equations and so that The dynamic equation is and its constriction is give by
96 EXACT SOLUTIONS AND SCALAR FIELDS IN GRAVITY Even if these last two equations do not contain the scale factor that with other fluids is always present. This fact makes it unnecessary recourse to a third order differential equation in order to eliminate the aforementioned term. For Eq.(25), and Eq.(26) obtain with while while remains free. The discriminant is In all, three different cosmic solutions for this FRW flat space model exist distinguished by the discriminant whose sign depends on the sign of The solutions have been analyzed in [7]. For Eq.(25) and Eq.(26) have the following solutions the first is for and with the second is for and and for the third, the last is for and Moreover, when depending on the sign of for each type of determinant one can get two solutions. Other particular solutions for are found when with so that This last expression can be given in terms of the “cosmic time The result is a linear expansion because, from the constriction one gets
