We obtain a constraint on cosmological scalars for the FRW metric with a pure radiation fluid source and positive cosmological constant. We demonstrate that this constraint is conformally invariant in the context of Penrose’s Conformal Cyclic Cosmology proposal, where the metrics of the late stages of the previous aeon and the early stages of the present aeon are described by FRW cosmologies.

Ellipsoidal expansion of the Universe, cosmic shear, acceleration and jerk parameter
Abstract.In order to study whether the anisotropy of the spacetime may induce differences in the cosmic shear or in the deceleration parameter, we investigate in the Bianchi I Universe the most


Cosmic jerk, snap and beyond
We clarify the procedure for expressing the Friedmann equation in terms of directly measurable cosmological scalars constructed out of higher derivatives of the scale factor. We carry out this
The equations of CCC
I review the equations of Conformal Cyclic Cosmology given by Penrose. I suggest a slight modification to Penrose's prescription and show how this works out for FRW cosmologies and for Class A
A fundamental solution to the CCC equations
We display a simple solution to the Penrose CCC scenario. For this solution we chose for the late stages of the previous aeon a FRW, $$\hbox {k}=0$$k=0, universe with both a cosmological constant and
Jerk, snap, and the cosmological equation of state
Taylor expanding the cosmological equation of state around the current epoch is the simplest model one can consider that does not make any a priori restrictions on the nature of the cosmological
Observational tests in cosmology
IT is often said that the determination of the deceleration term is one of the main aims of observational cosmology. In the following comments this view is questioned, and in a universe of
Statefinder—A new geometrical diagnostic of dark energy
It is demonstrated that the Statefinder diagnostic can effectively differentiate between different forms of dark energy and can be determined to very high accuracy from a SNAP-type experiment.
