薄壳虫孔的稳定性

On the stability of thin-shell wormholes

Peter K. F. Kuhfittig

摘要:

薄壳虫洞理论上可以通过所谓的剪切粘贴技术将两个史瓦西时空手术移植在一起来构建。通过描述这样的虫洞的球壳的极限情况下,它示出的结构必须是不稳定的线性径向扰动。然而,作者等人的一些早期研究表明,在某些条件下,薄壳虫洞可以是稳定的。

英文摘要:

A thin-shell wormhole is theoretically constructible by surgically grafting together two Schwarzschild spacetimes using the so-called cut-and-paste technique. By describing such a wormhole as the limiting case of a spherical shell, it is shown that the structure must be unstable to linearized radial perturbations. Some earlier studies by the author et al. have shown, however, that under certain conditions, thin-shell wormholes can be stable.
