广义宇宙Chaubergin气体支撑的Born-Infeld薄壳虫洞

Born-Infeld Thin-shell Wormholes Supported by Generalized Cosmic Chaplygin Gas

M. Azam

摘要:

本文研究了广义宇宙Chaubergin气体(GCCG)支持的Born-Infeld理论中的薄壳虫孔。我们研究了它们的稳定性通过径向扰动的不同值的电荷和Born-Infeld参数。比较了广义Chaubergin气体、修正Chaubergin气体与GCCG状态方程对应的虫孔解。结果表明,在小的电荷和Born-Infeld参数下,所有类型的状态方程都存在类似的虫洞解,而在大的电荷和Born-Infeld参数下,存在一些额外的稳定解和不稳定解.因此,可以得出结论,GCCG和大的电荷值可能是负责这些额外的解决方案。

英文摘要:

This paper investigates thin-shell wormholes in Born-Infeld theory supported by generalized Cosmic Chaplygin gas (GCCG). We study their stability via radial perturbations for distinct values of charge and Born-Infeld parameter. The comparison of wormhole solutions corresponding to generalized Chaplygin gas, modified Chaplygin gas with GCCG quation of state is established. It is found that similar type of wormhole solutions exists for small value of charge and Born-Infeld parameter for all type of equation of state, while some extra stable as well as unstable solution are found corresponding to large value of charge and Born-Infeld parameter. Thus, it is concluded that GCCG and large value of charge may responsible for such extra solutions.
