This paper explores the stable configuration of thin-shell wormholes constructed from two regular black holes (modified Hayward and four parametric) by using Visser cut and paste approach. The components of stress-energy tensor are evaluated through the Lanczos equations. We analyze the stability of thin-shell by using radial perturbation preserving its symmetries about equilibrium static solution. It is found that modified Hayward wormholes are more stable than the Hayward wormholes. Further, the stable regions of four parametric regular wormholes are larger than the Schwarzschild, Reissner–Nordström and Ayón–Beato–García wormholes. We conclude that stable region decreases for highly charged thin-shell wormholes.

一类规则薄壳虫洞的力学稳定性

本文探讨了使用 Visser 剪切和粘贴方法由两个常规黑洞(改进的 Hayward 和四参数)构建的薄壳虫洞的稳定构型。通过 Lanczos 方程评估应力-能量张量的分量。我们通过使用径向扰动来分析薄壳的稳定性,保持其关于平衡静态解的对称性。发现修改后的海沃德虫洞比海沃德虫洞更稳定。此外,四个参数规则虫洞的稳定区域比 Schwarzschild、Reissner-Nordström 和 Ayón-Beato-García 虫洞大。我们得出结论,高电荷薄壳虫洞的稳定区域减小。
