Charged shells in a 2+1 dimensional spacetime [PDF]
Ernesto F. Eiroa, Claudio SimeoneWe study circular shells in a 2+1 dimensional background within the framework of Einstein-Born-Infeld theory. For shells around black holes we analyze the mechanical stability under perturbations preserving the symmetry. Shells around vacuum are also discussed. We find a large range in the values of the parameters compatible with stable configurations.View original: http://arxiv.org/abs/1301.0851
