Abstract

We extend our previous analysis of a model for "dark energy" based on a Weyl scaling invariant dark energy action. We reexpress all prior results in terms of proper time, using the fluctuation amplitude Φ\Phi without approximation, and derive a compact formula for the squared effective Hubble parameter. This formula involves effective dark energy and matter densities that differ from their expressions in the standard ΛCDM\Lambda CDM cosmology. We also give new analytic results for the function Φ \Phi and discuss their implications.
