Exact Solutions for Cosmological Models with a Scalar Field

High Energy Physics - Theory 2007-05-23 v2

Abstract

We consider the existence of a Noether symmetry in the scalar-tensor theory of gravity in flat Friedman Robertson Walker (FRW) cosmology. The forms of coupling function ω(ϕ)\omega(\phi) and generic potential V(ϕ)V(\phi) are obtained by requiring the existence of a Noether symmetry for such theory. We derive exact cosmological solutions of the field equations from a point-like Lagrangian.
