On the Local Extension of Killing Vector-Fields in Ricci Flat Manifolds

Speaker: Alex Ionescu, Princeton University

Location: Warren Weaver Hall 1302

Date: Thursday, November 3, 2011, 11 a.m.

Synopsis:

I will discuss some recent work, joint with S. Klainerman, on the problem of extension of Killing vector-fields in manifolds that satisfy the Einstein vacuum equations. This problem is motivated by the black hole rigidity conjecture, concerning the uniqueness of the Kerr family among regular, stationary black hole solutions of the Einstein vacuum equations.
