T-duality and high-derivative gravity theories: the BTZ black hole/string paradigm

Jose D. Edelstein, Konstantinos Sfetsos, J. Anibal Sierra-Garcia +1

We show that the temperature and entropy of a BTZ black hole are invariant under T-duality to next to leading order in $M_{\star }^{-2}$, $M_{\star }$ being the scale suppressing higher-…
