             Inner horizon instability of black holes

             Monday, 18. June 2018, 14:00 c.t.
        Lecture room W2 3-349, University of Oldenburg

ABSTRACT:

It is generally believed the inner horizon of a charged or rotating
black hole in asymptotically flat spacetime is a singular surface.
The singularity arises due to the backreaction of blue-shifted perturbation
near the inner horizon. Poisson-Israel first studied this back-reaction for a
charged black hole and found there is an unbounded increase of black hole's
internal mass parameter - known as 'mass inflation' instability.
Ori constructed a simple model of this phenomenon and determined an exact
solution in the mass inflation region.

In this talk we discuss the Ori model for charged AdS black holes. We also
discuss the nature and strength of the singularity.
