受引力波、暗物质与暗能量相互作用的启发,我们针对Bondi-Sachs度规研究带非零宇宙学常数的爱因斯坦标量场方程,给出了出射辐射条件下的渐近展开。与零宇宙学常数情形不同,该渐近展开依赖四个额外的Λ无关函数:B(u,θ,φ)、X̃(u,θ,φ)、Ỹ(u,θ,φ)与Ĩ(u)。我们证明,在合适的坐标变换下可令B(u,θ,φ)=0;当Ĩ=0时,我们建立了该方程的剥离性质,并推导了非零宇宙学常数下Bondi能量-动量的损失公式,指出该公式对部分来自引力波的真实数据,可能体现Bondi能量-动量的损失性质。

英文摘要

Inspired by interaction of gravitational waves, dark matters and dark energy, we study the Einstein scalar field equations with the nonzero cosmological constant for the Bondi-Sachs metrics. We provide the asymptotic expansions under the outgoing radiation condition. Unlike the case of the zero cosmological constant, the asymptotic expansions depend on four additional $Λ$-independent functions $B(u, θ, ϕ)$, $\tilde{X}(u, θ, ϕ)$, $\tilde{Y}(u, θ, ϕ)$ and $\tilde{I}(u)$. We show that, under suitable coordinate transformation, we can make $B(u, θ, ϕ)=0$. We prove the peeling property for the Einstein scalar field equations if $\tilde{I}=0$, and derive a loss formula of the Bondi energy-momentum for the nonzero cosmological constant. We remark that, for certain real data from gravitational waves, the loss formula is likely to indicate the loss property of the Bondi energy-momentum.
