Thin-shell wormholes associated with global cosmic strings
Cecilia Bejarano, Ernesto F. Eiroa, Claudio Simeone
Abstract
In this article we construct cylindrical thin-shell wormholes in the context of global cosmic strings. We study the stability of static configurations under perturbations preserving the symmetry and we find that the throat tends to collapse or expand, depending only on the direction of the velocity perturbation.
