It is proved that the multipole moments of a stationary, asymptotically flat system in general relativity theory as defined by Thorne are identical, aside from normalization, to those defined by Geroch and Hansen:
Here
is Thorne's mass moment of orderl,
is the Geroch-Hansen mass moment,
is Thorne's current moment of orderl, and
is Hansen's current moment. The mathematical techniques of Thorne are combined with those of Geroch and Hansen to prove several new theorems about multipole moments, and to give new proofs to some of the old theorems.
