论文摘要
我们通过研究在平坦时空中的Pauli-Fierz Spin-2理论中，通过研究了可能从递归的nöther耦合方法中调整可能的扣除来解决在当前重力波文献中广泛使用的问题。我们发现，这种方法可以正确地将后者的近似值带到前三个顺序，而无需调用任何一般相对性的弱场限制。因此，这种联系确定了辛科夫斯基的近似具有独立的含义，与一般相对性的弱场扩张无关，这是文献中通常呈现的方式。因此，链接表现出递归的nöther耦合方法，从平面时期的线性自旋2理论和最近检测引力波事件的理论分析中得出一般相对论。
We address the problem of deriving the post-Minkowskian approximation, widely used in current gravitational wave literature by investigating a possible deduction out of the recursive Nöther coupling approach, from the Pauli-Fierz spin-2 theory in flat spacetime. We find that this approach yields the post-Minkowskian approximation correctly to the first three orders, without invoking any weak-field limit of general relativity. This connection thus establishes that the post-Minkowskian approximation has a connotation independent of a weak-field expansion of general relativity, which is the manner usually presented in the literature. As a consequence, a link manifests between the recursive Nöther coupling approach to deriving general relativity from a linear spin-2 theory in flat spacetime and theoretical analyses of recent detection of gravitational wave events.
