Abstract: (arXiv)
We analyze in detail the highly damped quasinormal modes of D-dimensional extremal Reissner-Nordstrm and Reissner-Nordstrm-de Sitter black holes. We only consider the extremal case where the event horizon and the Cauchy inner horizon coincide. We show that, even though the topology of the Stokes/anti-Stokes lines in the extremal case is different than the non-extremal case, the highly damped quasinormal mode frequencies of extremal black holes match exactly with the extremal limit of the non-extremal black hole quasinormal mode frequencies.Note:

- space-time: de Sitter
- black hole: quasinormal mode
- WKB approximation
- black hole: Reissner-Nordstroem
- monodromy
- higher-dimensional
