研究了轴对称时空中的角动量。这些结论得到了一个适用于所有渐近平坦空间的一般定义，该定义在无限远和黑洞的视界上都是有效的。第一篇论文将注意力限制在无穷远的考虑上。根据自旋系数形式，在大距离上对场方程进行了渐近求解，并对定义进行了评价。导出了一个守恒定律，并讨论了坐标的超平移对角动量的影响。
Angular momentum in axisymmetric space-times is investigated. The conclusions lead to a general definition suitable for all asymptoticallyflat spaces which is valid both at infinity and on the event horizon of a black hole. This first paper restricts attention to considerations at infinity. Working in terms of the spin coefficient formalism, the field equations are solved asymptotically at large distances and the definition is evaluated. A conservation law is derived and finally the effect on the angular momentum of a supertranslation of the coordinates is discussed.
