Mixmaster Behavior in Inhomogeneous Cosmological Spacetimes
Marsha Weaver, James Isenberg, Beverly K. Berger
Numerical investigation of a class of inhomogeneous cosmological spacetimes shows evidence that at a generic point in space the evolution toward the initial singularity is asymptot…
Phenomenology of the Gowdy Universe on
Beverly K. Berger, David Garfinkle
Numerical studies of the plane symmetric, vacuum Gowdy universe on yield strong support for the conjectured asymptotically velocity term dominated (AVTD) behavior of…
Numerical Study of Cosmological Singularities
B. K. Berger, D. Garfinkle, V. Moncrief
The spatially homogeneous, isotropic Standard Cosmological Model appears to describe our Universe reasonably well. However, Einstein's equations allow a much larger class of cosmol…
Comment on ``The Gowdy Cosmologies Revisited''
Beverly K. Berger, David Garfinkle, Vincent Moncrief
A standard and reasonable definition of asymptotic velocity term dominance (AVTD) shows that the numerical study by Hern and Stewart (gr-qc/9708038) confirms previous results that…
Global Foliations of Vacuum Spacetimes with Isometry
Beverly K. Berger, James Isenberg, Piotr T. Chruściel +1
We prove a global existence theorem (with respect to a geometrically- defined time) for globally hyperbolic solutions of the vacuum Einstein equations which admit a isometry…
