论文摘要
我们考虑在异性超弦的圆圈上的紧凑型有效的动作，以在regge Slope参数$α'$中进行一阶，并重新启用$α'$ - 校正的Buscher规则，在Arxiv：Hep-Th/9506156中首先证明，证明了Diperensionally Innveariance in Dipensionally Invancience in Dismensionally Invancience in Dismensionally Invectionally distersive diste $ a $ a $ a'''''''''。我们使用IYER和WALD的处方来得出一个熵公式，该公式可以应用于黑洞溶液，该溶液可以通过圆圈上的单个非平凡的压实来获得，并在$α'$校正的t二元转换下讨论其不变性。该公式已成功地应用于$α'$ - 校正的4维非超级reissner-reissner-nordström黑洞：1910.14324，我们在此处将其应用于Strominger-VAFA极好的5-维5维的异性版。
We consider the compactification on a circle of the Heterotic Superstring effective action to first order in the Regge slope parameter $α'$ and re-derive the $α'$-corrected Buscher rules first found in arXiv:hep-th/9506156 , proving the T duality invariance of the dimensionally-reduced action to that order in $α'$. We use Iyer and Wald's prescription to derive an entropy formula that can be applied to black-hole solutions which can be obtained by a single non-trivial compactification on a circle and discuss its invariance under the $α'$-corrected T duality transformations. This formula has been successfully applied to $α'$-corrected 4-dimensional non-extremal Reissner-Nordström black holes in arXiv:1910.14324 and we apply it here to a heterotic version of the Strominger-Vafa 5-dimensional extremal black hole.
