Application of Discrete Differential Forms in numerical General Relativity — •Ronny Richter — Universität Tübingen: Institut für Astronomie und Astrophysik — Mathematisches Institut

We discuss a way to apply Discrete Differential Forms in numerical General Relativity. The method was used for the space-time discretisation of systems with large symmetry groups, like spherically symmetric ones. The results of numerical tests are quite promising. In particular the error converges quadratically to zero with the discretisation parameter.
