SUMMARY:Seminar Analysis and Mathematical Physics: Christoph Kehle (ETH Zü
 rich)
DESCRIPTION:Extremal black holes are special types of black holes which hav
 e exactly zero temperature. I will present a proof that extremal black hol
 es form in finite time in gravitational collapse of charged matter. In par
 ticular\, this construction provides a definitive disproof of the “third
  law” of black hole thermodynamics. I will also present a recent result 
 which shows that extremal black holes arise on the black hole formation th
 reshold in the moduli space of gravitational collapse. This gives rise to 
 a new conjectural picture of “extremal critical collapse.” This is joi
 nt work with Ryan Unger (Princeton).
