论文摘要
这项研究旨在研究可行的对数F（r）重力在给出虫孔溶液中通胀的可行性。我们考虑静态和球形对称的时空和两个不同的形状函数。我们发现该模型提供了可侵蚀虫洞的溶液，该溶液违反了能量条件。违反无效的能量条件表明存在可穿越的虫洞和异国物质的存在。状态参数的方程小于-1，显示幻象流体的存在。此外，使用Tolman-Oppenheimer-Volkoff方程来分析虫洞的稳定性，我们发现虫洞溶液是稳定的。最后，我们得出的结论是，该模型可以可行，可以提供与通货膨胀相同的参数约束的虫洞溶液。
This study aims to investigate the viability of a viable logarithmic f(R) gravity for inflation in giving wormhole solutions. We consider a static and spherically symmetric spacetime and two different shape functions. We found that the model provides traversable wormhole solutions shown by its violation to energy conditions. Violation to null energy condition indicates the existence of traversable wormhole and the existence of exotic matter. The equation of state parameter is less than -1 which shows the presence of phantom fluid. Furthermore, the stability of wormhole is analyzed using Tolman-Oppenheimer-Volkoff equation and we found that the wormhole solutions are stable. Finally, we conclude that the model is viable in giving wormhole solutions with the same parameter constraints as inflation.
