【 摘 要 】

We show that the Riemannian Schwarzschild and the Taub-bolt instanton solutions are the only spaces (M, g(mu nu)) such that: M is a four-dimensional, simply connected manifold with a Riemannian, Ricci-flat C-2-metric g(mu nu) which admits (at least) a 1-parameter group mu(tau) of isometries without isolated fixed points on M. The quotient (M \ L-M)/mu(tau) (where L-M is the set of fixed points of mu(tau)) is an asymptotically flat manifold, and the length of the Killing field corresponding to mu(tau) tends to a constant at infinity.
