Some general aspects of thin-shell wormholes with cylindrical symmetry

Understand

In this article we study a general class of non-rotating thin-shell wormholes with cylindrical symmetry.

• We consider two physically sound definitions of the flare-out condition and we show that the less restrictive one allows for the construction of wormholes with positive energy density at the throat.
• We also analyze the mechanical stability of these objects under perturbations preserving the symmetry, proving that previous results are particular cases of a general property.
• We present examples of wormholes corresponding to Einstein-Maxwell spacetimes.
