Asymptotic Behavior of a Class of Expanding Gowdy Spacetimes
Beverly K. Berger
A systematic asymptotic expansion is developed for the gravitational wave degrees of freedom of a class of expanding, vacuum Gowdy cosmological spacetimes. In the wave map descript…
Report on A5. Computer Methods
Beverly K. Berger
Session A5 on numerical methods contained talks on colliding black holes, critical phenomena, investigation of singularities, and computer algebra.
Approach to the Singularity in Spatially Inhomogeneous Cosmologies
Beverly K. Berger
A combination of analytic and numerical methods has yielded a clear understanding of the approach to the singularity in spatially inhomogeneous cosmologies. Strong support is found…
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…
Numerical Investigation of Singularities
Beverly K. Berger
Numerical exploration of the properties of singularities could, in principle, yield detailed understanding of their nature in physically realistic cases. Examples of numerical inve…
