Staticity, Self-Similarity and Critical Phenomena in a Self-Gravitating Nonlinear Sigma Model
Christiane Lechner
The main part of the thesis deals with continuously and discretely self-similar solutions and type II critical phenomena in a family of self-gravitating non-linear sigma-models. Th…

Computer Algebra Applications for Numerical Relativity
Sascha Husa, Christiane Lechner
We discuss the application of computer algebra to problems commonly arising in numerical relativity, such as the derivation of 3+1-splits, manipulation of evolution equations and a…

Episodic Self-Similarity in Critical Gravitational Collapse
J. Thornburg, Ch. Lechner, M. Purrer +2
We report on a new behavior found in numerical simulations of spherically symmetric gravitational collapse in self-gravitating SU(2) sigma models at intermediate gravitational coup…
