Are maximal analytic extensions of the Kerr and Kerr-Newman spacetimes
physically meaningful?    [PDF]

H. Garcia-Compean, V. S. Manko

We argue that the well-known maximal analytic extensions of the Kerr and Kerr-Newman spacetimes characterized by two asymptotically flat regions with ADM masses of opposite signs are physically inconsistent. The noncontradictory extensions are proposed.
