Abstract
We describe the smooth transition from vacuum p = -epsilon into dust, by postulating the time dependence of the gamma parameter in the state equation for the scalar field driving inflation and giving masses to particles. In this sense we study the dynamics of inflation without as suming slow rolling. We proceed backwise to reconstruct the scalar fie ld potential for the Klein-Gordon equation.
