An exact solution for 2+1 dimensional critical collapse
David Garfinkle
We find an exact solution in closed form for the critical collapse of a scalar field with cosmological constant in 2+1 dimensions. This solution agrees with the numerical simulatio…
Numerical evolution of Brill waves
David Garfinkle, G. Comer Duncan
We report a numerical evolution of axisymmetric Brill waves. The numerical algorithm has new features, including (i) a method for keeping the metric regular on the axis and (ii) th…
Generalized entropy and Noether charge
David Garfinkle, Robert Mann
We find an expression for the generalized gravitational entropy of Hawking in terms of Noether charge. As an example, the entropy of the Taub-Bolt spacetime is calculated.
Existence, uniqueness and other properties of the BCT (minimal strain lapse and shift) gauge
David Garfinkle, Carsten Gundlach, James Isenberg +1
Brady, Creighton and Thorne have proposed a choice of the lapse and shift for numerical evolutions in general relativity that extremizes a measure of the rate of change of the thre…
