论文摘要
已直接检测到引力波,天文观测表明我们的宇宙具有正宇宙常数$λ$。然而,在正面$λ$的存在下,在无限的引力波(从时空逃脱)的理论规格不变概念是难以捉摸的。我们找到了这个长期存在的引力拼图的答案,并提出了无穷大的几何量规辐射条件。
Gravitational waves have been directly detected and astronomical observations indicate that our Universe has a positive cosmological constant $Λ$. Nevertheless, a theoretical gauge-invariant notion of gravitational waves arriving at infinity (escaping from the space-time) in the presence of a positive $Λ$ has been elusive. We find the answer to this long-standing gravitational puzzle and present a geometric, gauge-invariant radiation condition at infinity.
