Gravitational hedgehog, stringy hedgehog and stringy sphere
arXiv:gr-qc/0307099 · doi:10.1088/1126-6708/2003/11/058
Abstract
We investigate the solutions of Einstein equations such that a hedgehog solution is matched to different exterior or interior solutions via a spherical shell. In the case where both the exterior and the interior regions are hedgehog solutions or one of them is flat, the resulting spherical shell becomes a stringy shell. We also consider more general matchings and see that in this case the shell deviates from its stringy character.
