Aliasing Instabilities in the Numerical Evolution of the Einstein Field Equations
Claudio Meringolo, Sergio Servidio
The Einstein field equations of gravitation are characterized by cross-scale, high-order nonlinear terms, representing a challenge for numerical modeling. In an exact spectral deco…

Extreme Gravitational Interactions in the Problem of Three Black Holes in General Relativity
Mario Imbrogno, Claudio Meringolo, Sergio Servidio
We study the three-body problem going from Newtonian mechanics to general relativity. In the classical case, we model the interactions in a typical chaotic configuration, identifyi…
