Existence, uniqueness and other properties of the BCT (minimal strain lapse and shift) gauge

Existence, uniqueness and other properties of the BCT (minimal strain lapse and shift) gauge
Existence, uniqueness and other properties of the BCT (minimal strain lapse and shift) gauge
Brady, Creighton and Thorne (BCT) 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 3-metric (BCT gauge). We investigate the existence and uniqueness of this gauge (with Dirichlet boundary conditions), and comment on its use in numerical time evolutions.

Abstract

Brady, Creighton and Thorne (BCT) 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 3-metric (BCT gauge). We investigate the existence and uniqueness of this gauge (with Dirichlet boundary conditions), and comment on its use in numerical time evolutions.
