摘要
This note describes how to characterize and normalize an axial Killing field on a general Riemannian geometry or four-dimensional Lorentzian geometry. No global assumptions are necessary, such as that the orbits of the Killing field all have period 2 pi. Rather, any Killing field that vanishes at at least one point necessarily has the expected global properties.
