Were strong inflaton field fluctuations the cause of the big bang?

Abstract

In this paper, I propose a model to describe the birth of the universe taking into account back reaction effects produced by the inflaton field fluctuations, with self-interactions included. These fluctuations δφ = φ(x) -(φ) would have been very important at the Planck scales and their self-interactions could have been the fuel to the primordial expansion of the universe.
