Cosmological global dynamical systems analysis
Artur Alho, Woei Chet Lim, Claes Uggla
We consider a dynamical systems formulation for models with an exponential scalar field and matter with a linear equation of state in a spatially flat and isotropic spacetime. In c…
Non-orthogonally transitive spike solution
Woei Chet Lim
We generalize the orthogonally transitive (OT) spike solution to the non-OT case. This is achieved by applying Geroch's transformation on a Kasner seed. The new solutio…
Spherically symmetric cosmological spacetimes with dust and radiation - numerical implementation
Woei Chet Lim, Marco Regis, Chris Clarkson
We present new numerical cosmological solutions of the Einstein Field Equations. The spacetime is spherically symmetric with a source of dust and radiation approximated as a perfec…
The electromagnetic spike solutions
Ernesto Nungesser, Woei Chet Lim
The aim of this paper is to use the existing relation between polarized electromagnetic Gowdy spacetimes and vacuum Gowdy spacetimes to find explicit solutions for electromagnetic…
Spike Oscillations
J. Mark Heinzle, Claes Uggla, Woei Chet Lim
According to Belinskii, Khalatnikov and Lifshitz (BKL), a generic spacelike singularity is characterized by asymptotic locality: Asymptotically, toward the singularity, each spatia…
Future asymptotics of tilted Bianchi type II cosmologies
Sigbjorn Hervik, Woei Chet Lim, Patrik Sandin +1
In this paper we study the future asymptotics of spatially homogeneous Bianchi type II cosmologies with a tilted perfect fluid with a linear equation of state. By means of Hamilton…
