Global dynamics of two models for Quintom Friedman-Lemaître-Robertson-Walker Universes
Genly Leon, Alan Coley, Andronikos Paliathanasis +2
We comprehensively analyze the dynamics for the gravitational field equations for the Chiral-Quintom theory in a Friedman-Lemaître-Robertson-Walker cosmology with an additional mat…
Spatially Homogeneous Teleparallel Gravity: Bianchi I
A. A. Coley, R. J. van den Hoogen
Using a recently developed algorithm that chooses preferred coordinates and a preferred co-frame, we will determine the completely general Bianchi type I teleparallel geometry. In…
The equilibrium condition in gravitational collapse and its application to a cosmological scenario
Dipanjan Dey, N. T. Layden, A. A. Coley +1
We discuss the equilibrium conditions of the gravitational collapse of a spherically symmetric matter cloud. We analyze the spinor structure of a general collapsing space-time and…
A frame based approach to computing symmetries with non-trivial isotropy groups
D. D. McNutt, A. A. Coley, R. J. van den Hoogen
A frame approach to determining the most general solution admitting a desired symmetry group has been examined previously in Riemannian and teleparallel geometries with some succes…
Teleparallel Geometry with a Single Affine Symmetry
Alan Coley, Robert van den Hoogen
In teleparallel geometries, symmetries are represented by affine frame symmetries which constrain both the (co)frame basis and the spin-connection (which are the primary geometric…
The dynamics of scalar-field Quintom cosmological models
Jonathan Tot, Balkar Yildirim, Alan Coley +1
We shall present a complete (compactified) dynamical systems analysis of the Quintom model comprised of an interacting quintessence scalar field and a phantom. We find a range for…
