论文摘要
我们认为非本地重力可以获得稳定且可穿越的虫洞溶液。特别地，考虑到重力作用中的非本地积分核理论，具有反向d'AlemberT算子。我们获得了无效能量条件的约束并得出场方程。假定相关的Klein-Gordon方程的两种特殊情况：一种在重力作用中的功能具有线性形式，另一种具有指数形式的形式。在每种情况下，我们都考虑到标量字段的两种形式并得出形状函数。检查渐近平坦度和爆发条件。在喉咙上检查了溶液的能量条件和动力学。主要结果是非本地重力贡献允许蠕虫孔的稳定性和遍历性，而无需考虑任何异国情调。
We consider Non-local Gravity in view to obtain stable and traversable wormhole solutions. In particular, the class of Non-local Integral Kernel Theories of Gravity, with the inverse d'Alembert operator in the gravitational action, is taken into account. We obtain constraints for the null energy condition and derive the field equations. Two special cases for the related Klein-Gordon equation are assumed: one where the function in the gravitational action has a linear form and another one with exponential form. In each case, we take into account two forms for scalar fields and derive the shape functions. Asymptotic flatness and flaring-out conditions are checked. Energy conditions and dynamics of the solutions are examined at the throat. The main result is that non-local gravity contributions allow stability and traversability of the wormhole without considering any exotic matter.
