Apparent Horizon Finding — •Norbert Lages — Friedrich-Schiller-Universität Jena, Deutschland

First a brief summary is given of why Apparent Horizons or more generally Marginally Trapped Surfaces (MOTs) are interesting in numerical Relativity.

Special methods are explained for how to find MOTs in axisymmetry and MOTs in arbitrary (conformally flat) spacetimes. I will present a method to extract the eigenvalues of a Newton-type iteration procedure and its possible applications to improve Apparent Horizon finding.
