Black hole entropy, T-duality and high-derivative gravity theories
- Dr. J. Anibal SIERRA-GARCIA
I consider a two-parameter family of higher-derivative gravitational actions exhibiting T-duality. Some values of the parameters correspond to string theory effective actions, but most of them do not. For all cases, I will show black hole entropy and temperature to be invariant under T-duality. As an explicit example, BTZ black hole and its T-dual black string are presented.
