SUMMARY:The Teukolsky equations in Kerr-Newman spacetime - Elena Giorgi (P

DESCRIPTION:The Kerr-Newman spacetime is the most general explicit black h
 ole solution\, and represents a stationary rotating charged black hole. It
 s stability to gravitational and electromagnetic perturbations has eluded 
 a proof since the 80s in the black hole perturbation community\, because o
 f "the apparent indissolubility of the coupling between the spin-1 and spi
 n-2 fields in the perturbed spacetime"\, as put by Chandrasekhar. We will 
 present a derivation of the Teukolsky equations in Kerr-Newman in physical
  space and use it to obtain a quantitative proof of stability.
