摘要

在本文中，我们利用Darmois-Israel结的形式理论构造了一个（2 + 1）维旋转薄壳虫洞。这种薄壳虫洞的有效性已经通过分析能量条件，特别是弱能量和零能量条件来验证，它实际上是通过剪切和粘贴两个旋转的（2+1）维毛茸茸的黑洞时空来构建的。我们进一步讨论了所构建虫洞的不同物理特征，即引力场的性质、喉口处的状态方程和喉口半径的时间演化。我们还通过研究在小扰动下的运动方程来分析薄壳虫洞的稳定性。

Thin shell wormhole from rotating hairy black hole in (2+1)-dimensions

In this article, we theoretically construct a (2 + 1)-dimensional rotating thin shell wormhole using the Darmois-Israel junction formalism. This thin shell wormhole whose validity has been checked by analyzing the energy conditions, specifically, the weak and null energy conditions, is actually constructed by cutting and pasting two rotating hairy black hole spacetimes in (2+1)-dimensions. We further discuss different physical features of the constructed wormhole, viz., the nature of the gravitational field, the equation of state at the throat, and the time evolution of the throat radius. We also analyze the stability of the thin shell wormhole by investigating the equation of motion under small perturbations.
