We study the stability of a scalar inflaton field and analyze its point attractors in the phase space. We show that the value of the inflaton held in the vacuum is a bifurcation parameter and prove the possible existence of a limit cycle by using analytical and numerical arguments.

Abstract
We study the stability of a scalar inflaton field and analyze its point attractors in the phase space. We show that the value of the inflaton held in the vacuum is a bifurcation parameter and prove the possible existence of a limit cycle by using analytical and numerical arguments.File in questo prodotto:
