SUMMARY:The classification of black holes - Dr Harvey Reall ( DAMTP)

DESCRIPTION:I will provide a gentle introduction to the problem of classif
 ying black hole solutions of the Einstein equation (the equation of motion
  of General Relativity). Uniqueness theorems proved in the 1970s indicate 
 that\, in three spatial dimensions\, a time-independent black hole is desc
 ribed by the Kerr solution\, which depends on just 2 parameters: the mass 
 and angular momentum of the hole. However\, in four spatial dimensions\, t
 here exist black holes with non-spherical topology as well as generalizati
 ons of the Kerr solution. Thus the classification problem is much more com
 plicated in higher dimensions. I will describe the results that have been 
 proved so far and the open problems that remain.
