Periodic self-similar wave maps coupled to gravity
arXiv:gr-qc/0310038 · doi:10.1103/PhysRevD.69.064014
Abstract
We continue our studies of spherically symmetric self-similar solutions in the SU(2) sigma model coupled to gravity. Using mixed numerical and analytical methods we show existence of an unstable periodic solution lying at the boundary between the basins of two generic attractors.
