Black hole entropy and $T$-duality with $\alpha'$ corrections
It is known from the work of Horowitz and Welch that in supergravity black hole entropy is invariant under the action of $T$-duality. What happens when $\alpha'$ corrections are included? I will present an $\alpha'$ corrected family of actions -including Type II, bosonic and heterotic strings- that enjoy $T$-duality symmetry. After that, I will show the form of the entropy and its behaviour under the corrected T-duality.
