论文摘要
在本文中，我们测试了在四个维度的一般相对论的背景下，建立新的黑手弹空间的可能性。这些新指标可以呈现额外的结构，例如抗喉咙。我们看到该区域进入无穷大的两个区域，并且根据模型，其中一个区域呈现曲率奇异性。常规指标可以扩展到径向坐标的负值，并具有对称结构，而某些单数则不能扩展，并且没有对称结构。分析了能量条件，在某些情况下，无效条件下的至少一种不平等现象不受尊重。我们还提出了满足事件视野之外的无效状态的模型。事件范围隐藏了这些模型的喉咙。
In this article, we test the possibility of building new black-bounce spacetimes with changes in the area in the context of general relativity in four dimensions. These new metrics can present extra structures, such as anti-throats. We see two regions where the area goes to infinity, and, depending on the model, one of these regions presents curvature singularities. Regular metrics can be extended to negative values of the radial coordinate and have a symmetrical structure, whereas some singular cases cannot be extended and have no symmetrical structure. The energy conditions are analyzed, and, for some cases, at least one of the inequalities in the null energy condition is not respected. We also presented models that satisfied the null energy condition outside the event horizon. The event horizon hides the throats of these models.
