摘要

在最近的研究中,我们将在重力的框架下用Hu-Sawicki模型来研究虫洞模型。考虑球静力对称时空构造具有各向异性流体分布的虫洞模型。通过施加一个特定的状态方程来讨论无迹物质。为了解决虫洞几何形状函数的重要条件,我们使用了相关参数的特定值。此外,还讨论了不同的能量条件,以根据两种特定的模型来检验物质的性质。观察到两种模型都不符合零能条件。它提到我们的询价结果是可以接受的。

Wormhole Models and Energy Conditions in f ℛ Gravity with the Hu–Sawicki Model
In this recent study, we shall investigate the wormhole models with a Hu–Sawicki model in the framework of gravity. Spherically static symmetric space-time is considered to construct wormhole models with the anisotropic fluid distribution. The traceless matter is discussed by imposing a particular equation of state. To address the important conditions of the shape function of the wormhole geometry, we have used the particular values of the involved parameters. Furthermore, different energy conditions are discussed to check the nature of matter against two specific models. The null energy condition is observed to be violated for both of the models. It is mentioned that our inquired results are acceptable.
