论文摘要
我们考虑$ f（r，t）$重力理论，其中重力拉格朗日是由RICCI标量的任意功能和能量 - 摩托张量的痕迹给出的，以研究静态的球形对称蠕虫孔的几何形状，由物质源用同位素压力来源。根据对虫洞几何形状的限制，我们仔细采用不同的策略来构建具有虫洞特性和特征的解决方案。使用完全一般的程序，我们提供了几个虫洞的例子，其中螺纹螺纹蠕虫喉咙的物质满足了所有能量条件，并讨论了找到它们的一般机制。最后，我们假设一个平稳的转换，用于简化非线性场方程，并且比其他方程更一致，以得出结论，可以将结果视为不存在外来物质的特定精确虫洞溶液。
We consider $f(R, T)$ theory of gravity, in which the gravitational Lagrangian is given by an arbitrary function of the Ricci scalar and the trace of the energy-momentum tensor, to study static spherically symmetric wormhole geometries sustained by matter sources with isotropic pressure. According to restrictions on the wormhole geometries, we carefully adopt different strategies to construct solutions with the properties and characteristics of wormholes. Using a completely general procedure, we provide several examples of wormholes in which the matter threading the wormhole throat satisfies all of the energy conditions and discuss general mechanisms for finding them. Finally, we postulate a smooth transformation for simplifying the nonlinear field equations and have more consistent results than the other ones to conclude that the results can be viewed as specific exact wormhole solutions without the presence of exotic matter.
