WebJun 4, 1998 · Geroch’s conjecture (Ref. 2) is that K acts transitively on all stationary axisymmetric vacuum solutions. The theorem of Hauser and Ernst (Ref. 20) states that a certain large subgroup of K acts multiply transitively on all solutions which are analytic in a neighborhood of a given point of the z axis.
