Numerical confirmations of joint spike transitions in cosmologies
Woei Chet Lim
We produce numerical evidence that the joint spike transitions between Kasner eras of cosmologies are described by the non-orthogonally transitive spike solution. A new…
Cylindrical spikes
Muhammad Zubair Ali Moughal, Woei Chet Lim
The Geroch/Stephani transformation is a solution-generating transformation, and may generate spiky solutions. The spikes in solutions generated so far are either early-time permane…
Stiff fluid spike solutions from Bianchi type V seed solutions
Daniele Gregoris, Woei Chet Lim, Alan Coley
In this paper we expand upon our previous work [1] by using the entire family of Bianchi type V stiff fluid solutions as seed solutions of the Stephani transformation. Among the ne…
Tilt and phantom cosmology
A. A. Coley, S. Hervik, W. C. Lim
We show that in tilting perfect fluid cosmological models with an ultra-radiative equation of state, generically the tilt becomes extreme at late times and, as the tilt instability…
The Futures of Bianchi type VII0 cosmologies with vorticity
S. Hervik, R. J. van den Hoogen, W. C. Lim +1
We use expansion-normalised variables to investigate the Bianchi type VII model with a tilted -law perfect fluid. We emphasize the late-time asymptotic dynamical behaviour o…
