我们考虑平稳时空的一般渐近表达式。利用Killing方程,我们将爱因斯坦方程的动力学自由度约化为入射引力波的自由度。可以得到该函数的一般形式。借助一个渐近代数特殊条件,证明了Newman-Penrose常数为零.
We consider the general asymptotic expression of stationary spacetime. Using the Killing equation, we reduce the dynamical freedom of the Einstein equation to the in-going gravitational wave Ψ0. The general form of this function can be obtained. With the help of an asymptotically algebraic special condition, we prove that all Newman–Penrose constants vanish.
