Recent analytical and numerical techniques applied to the Einstein equations
Dave Neilsen, Luis Lehner, Olivier Sarbach +1
Combining deeper insight of Einstein's equations with sophisticated numerical techniques promises the ability to construct accurate numerical implementations of these equations. We…
Boundary conditions for Einstein's field equations: Analytical and numerical analysis
Olivier Sarbach, Manuel Tiglio
Outer boundary conditions for strongly and symmetric hyperbolic formulations of 3D Einstein's field equations with a live gauge condition are discussed. The boundary conditions hav…
Critical bubbles and implications for critical black strings
Olivier Sarbach, Luis Lehner
We demonstrate the existence of gravitational critical phenomena in higher dimensional electrovac bubble spacetimes. To this end, we study linear fluctuations about families of sta…
On the well posedness of the Baumgarte-Shapiro-Shibata-Nakamura formulation of Einstein's field equations
Horst Beyer, Olivier Sarbach
We give a well posed initial value formulation of the Baumgarte-Shapiro-Shibata-Nakamura form of Einstein's equations with gauge conditions given by a Bona-Masso like slicing condi…
