Chaotic inflation in F(R) supergravity

Abstract

The bosonic f(R) gravity function is derived from a chiral F(R) supergravity model for the first time. We find an existence of the upper limit (or AdS bound) on the scalar curvature, as well as a solution with a vanishing cosmological constant. We compare our simple model of F(R) supergravity to the well known Starobinsky model of chaotic inflation.
