A fundamental conjecture in General Relativity asserts that the domain of outer communication of a regular, stationary, four dimensional, vacuum black hole is isometrically diffeomorphic to the domain of outer communication of a Kerr black hole. One expects, due to gravitational radiation, that general, asymptotically flat solutions of the Einstein-vacuum equations1 settle down, asymptotically, into a stationary regime. Thus the conjecture, if true, would characterize all possible asymptotic states of the general evolution. So far the conjecture has been resolved, by combining results of Hawking [2] Carter [1] and Robinson [3], under the additional hypothesis of non-degenerate horizons and real analyticity of the space-time. The assumption of real analyticity is both hard to justify on physical grounds and difficult to dispense of. I will discuss some recent work, joint with S. Klainerman, aimed at understanding this conjecture in the class of smooth manifolds. We develop a new strategy to bypass analyticity based on a tensorial characterization of the Kerr space-times, and new geometric Carleman estimates.
