Hubble parameter and related formulas for a Weyl scaling invariant dark energy action
Keyword(s):
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 [Formula: see text] 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 [Formula: see text] cosmology. We also give new analytic results for the function [Formula: see text] and discuss their implications.
