Spherical Self-Similar Solutions in Einstein-Multi-Scalar Gravity

General Relativity and Quantum Cosmology 2009-07-07 v1

Abstract

We consider a general non-linear sigma model coupled to Einstein gravity and show that in spherical symmetry and for a simple realization of self-similarity, the spacetime can be completely determined. We also examine some more specific matter models and discuss their relation to critical collapse.
