The Existence of Einstein Static Universes and their Stability in Fourth order Theories of Gravity
Rituparno Goswami, Naureen Goheer, Peter K. S. Dunsby
We investigate whether or not an Einstein Static universe is a solution to the cosmological equations in gravity. It is found that only one class of theories admits a…
Dynamical systems analysis of anisotropic cosmologies in -gravity
Naureen Goheer, Jannie A. Leach, Peter K. S. Dunsby
In this paper we study the dynamics of {\it orthogonal spatially homogeneous} Bianchi cosmologies in -gravity. We construct a compact state space by dividing the state space i…
Compactifying the state space for alternative theories of gravity
Naureen Goheer, Jannie A. Leach, Peter K. S. Dunsby
In this paper we address important issues surrounding the choice of variables when performing a dynamical systems analysis of alternative theories of gravity. We discuss the advant…
