Description

One of the most important topics in present research on theoretical cosmology is the behavior of scalar fields in the very early universe, since by means of their existence it is possible to explain some of the basic phenomena that have characterized the evolution of the universe to its present state. Analyzing the Klein-Gordon equation in a homogeneous, isotropic and spatially flat universe model, the authors find the conditions for the existence of a universe dominated by a scalar field in its early stages
