Contribution

It clarifies misconceptions about small black hole stability and scale radius duality, and presents new results on quasinormal modes in anti-de Sitter spacetime.

Findings

Clarified stability issues of small black holes

Discussed scale radius duality misconceptions

Presented recent quasinormal mode results and implications

Abstract

A very brief review is given of some of the developments leading to our current understanding of black holes in string theory. This is followed by a discussion of two possible misconceptions in this subject - one involving the stability of small black holes and the other involving scale radius duality. Finally, I describe some recent results concerning quasinormal modes of black holes in anti de Sitter spacetime, and their implications for strongly coupled conformal field theories (in various dimensions).
