Absorbing boundary conditions for Einstein's field equations
Olivier Sarbach
A common approach for the numerical simulation of wave propagation on a spatially unbounded domain is to truncate the domain via an artificial boundary, thus forming a finite compu…
Outer boundary conditions for Einstein's field equations in harmonic coordinates
Milton Ruiz, Oliver Rinne, Olivier Sarbach
We analyze Einstein's vacuum field equations in generalized harmonic coordinates on a compact spatial domain with boundaries. We specify a class of boundary conditions which is con…
Improved outer boundary conditions for Einstein's field equations
Luisa T. Buchman, Olivier C. A. Sarbach
In a recent article, we constructed a hierarchy B_L of outer boundary conditions for Einstein's field equations with the property that, for a spherical outer boundary, it is perfec…
Internal structure of Einstein-Yang-Mills-Dilaton black holes
O. Sarbach, N. Straumann, M. S. Volkov
We study the interior structure of the Einstein-Yang-Mills-Dilaton black holes as a function of the dilaton coupling constant . For the solutions have no inte…
