Near-Constant Mean Curvature Solutions of the Einstein Constraint Equations with Non-Negative Yamabe Metrics
James Isenberg, Adam Clausen, Paul T Allen
We show that sets of conformal data on closed manifolds with the metric in the positive or zero Yamabe class, and with the gradient of the mean curvature function sufficiently smal…
The Modelling of Degenerate Neck Pinch Singularities in Ricci Flow by Bryant Solitons
David Garfinkle, James Isenberg
In earlier work, carrying out numerical simulations of the Ricci flow of families of rotationally symmetric geometries on , we have found strong support for the contention that…
Waveless Approximation Theories of Gravity
James A. Isenberg
The analysis of a general multibody physical system governed by Einstein's equations in quite difficult, even if numerical methods (on a computer) are used. Some of the difficultie…
Areal Foliation and AVTD Behavior in T^2 Symmetric Spacetimes with Positive Cosmological Constant
Adam Clausen, James Isenberg
We prove a global foliation result, using areal time, for T^2 symmetric spacetimes with a positive cosmological constant. We then find a class of solutions that exhibit AVTD behavi…
