摘要：
This paper investigates stability of Bardeen thin-shell wormholes constructed by cut and paste technique. We use Israel formalism to evaluate surface energy density as well as pressure and check the behavior of energy conditions. The linearized stability of the respective thin-shell wormholes is investigated by using three choices of variable equation of state; two of them provide stability regions at equilibrium radius. We conclude that stable Bardeen wormhole solutions exist for particular values of equilibrium radius as well as equation of state parameter.
