On the area of the symmetry orbits in symmetric spacetimes with Vlasov matter
Marsha Weaver
This paper treats the global existence question for a collection of general relativistic collisionless particles, all having the same mass. The spacetimes considered are globally h…
High velocity spikes in Gowdy spacetimes
David Garfinkle, Marsha Weaver
We study the behavior of spiky features in Gowdy spacetimes. Spikes with velocity initially high are, generally, driven to low velocity. Let n be any integer greater than or equal…
On the area of the symmetry orbits in symmetric spacetimes
James Isenberg, Marsha Weaver
We obtain a global existence result for the Einstein equations. We show that in the maximal Cauchy development of vacuum symmetric initial data with nonvanishing twist consta…
Existence of CMC and constant areal time foliations in T^2 symmetric spacetimes with Vlasov matter
Hakan Andreasson, Alan D. Rendall, Marsha Weaver
The global structure of solutions of the Einstein equations coupled to the Vlasov equation is investigated in the presence of a two-dimensional symmetry group. It is shown that the…
Kasner-like behaviour for subcritical Einstein-matter systems
Thibault Damour, Marc Henneaux, Alan D. Rendall +1
Confirming previous heuristic analyses à la Belinskii-Khalatnikov-Lifshitz, it is rigorously proven that certain ``subcritical'' Einstein-matter systems exhibit a monotone, general…
Oscillatory approach to the singularity in vacuum spacetimes with isometry
Beverly K. Berger, James Isenberg, Marsha Weaver
We use qualitative arguments combined with numerical simulations to argue that, in the approach to the singularity in a vacuum solution of Einstein's equations with isometry,…
