DESCRIPTION:In the first part of this talk\, we will (briefly)
derive the original calculation by Hawking in 197
4 to determine the radiation given off by a black
hole\, giving the result in the form of an integra
l of a classical solution to the linear wave equat
ion.\nIn the second part of the talk\, we will tak
e this integral as a starting point\, and rigorous
ly calculate the radiation given off by a forming
spherically symmetric\, charged black hole. We wil
l show that for late times in its formation\, the
radiation given off approaches the limit predicted
by Hawking\, including the extremal case. We will
also calculate a bound on the rate at which this
limit is approached.
