SUMMARY:Gilbert Weinstein: Kerr Black Hole Uniqueness
LOCATION:Hill 705
DESCRIPTION:<p>Abstract:&nbsp;&nbsp;</p><p data-olk-copy-source="MessageBody">The no-ha
 ir theorem states that the only asymptotically flat stationary solutions of
  the Einstein vacuum equations are members of the Kerr family, parametrized
  by mass and angular momentum. Hawking’s rigidity theorem shows that under 
 the hypothesis of analyticity, any such solution is axially symmetric. For 
 axially symmetric solutions with a single connected event horizon, Robinson
  (1975) proved that the solution must be Kerr. However, the case of multipl
 e black holes has remained largely open. We settle this longstanding proble
 m and show that stationary, axially symmetric multiple black holes cannot b
 e in equilibrium by studying the associated harmonic maps with prescribed s
 ingularities. This is joint work with Qing Han, Marcus Khuri, and Jingang X
 iong.</p>
