The Einstein-Hamilton-Jacobi equation: searching the classical solution for barotropic FRW
The dynamical evolution of the scale factor of FRW cosmological model is presented, when the equation of state of the material content takes the form p =<img src="../../../../../img/revistas/rmf/v53s2/a15s1.jpg">ρ, <img src="../../../../../img/revistas/rmf/v53s2/a15s1.jpg" > or = constant, including the cosmological term. We use the WKB approximation and the relation with the Einstein-Hamilton-Jacobi equation to obtain the exact solutions.
