论文摘要
我们详细阐述了[Phys。莱特牧师。 123（2019）13，131302]，关于隐藏宇宙学常数的可能性，人们期望在普朗克规模上存在的复杂拓扑。我们构建一个微分方程统治$ \ langle k \ rangle $的时间演变，这是扩展标量的空间平均值。假设解决方案$ \ langle k \ rangle = 0 $，尽管存在较大的宇宙常数$λ$，我们表明这种解决方案似乎是不稳定的。
We elaborate on the proposal of [Phys. Rev. Lett. 123 (2019) 13, 131302], about the possibility of hiding the cosmological constant in the complicated topology that one expects to exist at the Planck scale. We build a differential equation ruling the time evolution of $\langle K\rangle$, the spatial average of the expansion scalar. Supposing that the solution $\langle K\rangle = 0$ exists despite the presence of a large cosmological constant $Λ$, we show that such solution seems to be unstable.
