Constraint-preserving boundary conditions in the Z4 Numerical Relativity formalism
C. Bona, T. Ledvinka, C. Palenzuela-Luque +1
The constraint-preserving approach, which aim is to provide consistent boundary conditions for Numerical Relativity simulations, is discussed in parallel with other recent developm…

A symmetry-breaking mechanism for the Z4 general-covariant evolution system
C. Bona, T. Ledvinka, C. Palenzuela +1
The general-covariant Z4 formalism is further analyzed. The gauge conditions are generalized with a view to Numerical Relativity applications and the conditions for obtaining stron…

General-covariant evolution formalism for Numerical Relativity
C. Bona, T. Ledvinka, C. Palenzuela +1
A general covariant extension of Einstein\'{}s field equations is considered with a view to Numerical Relativity applications. The basic variables are taken to be the metric tensor…
