Linearized stability analysis of thin-shell wormholes with a cosmological constant
Classical and quantum gravity
Spherically symmetric thin-shell wormholes in the presence of a cosmological constant are constructed applying the cut-and-paste technique implemented by Visser. Using the Darmois-Israel formalism the surface stresses, which are concentrated at the wormhole throat, are determined. This construction allows one to apply a dynamical analysis to the throat, considering linearized radial perturbations around static solutions. For a large positive cosmological constant, i.e., for the Schwarzschild-dedoi:10.1088/0264-9381/21/2/004 fatcat:mwriyr6pn5ftpo4c7dcs3dnz5e
