The Monotonicity of the Gravitational Entropy Scalar within Quiescent Cosmology
Philip Threlfall, Susan M. Scott
In this paper we show that Quiescent Cosmology [1, 2, 3] is consistent with Penrose's Weyl Curvature Hypothesis and the notion of gravitational entropy [4]. Gravitational entropy,…

Conformal Structures Admitted by a Class of FRW Cosmologies
Philip Threlfall, Susan M. Scott
In this paper we demonstrate that there are large classes of Friedmann-Robertson-Walker (FRW) cosmologies that admit isotropic conformal structures of Quiescent Cosmology. FRW mode…
