论文摘要
我们计算了Riemann Tensor的第四强度的宇宙学降低，声称在弦理论中以$α'^{\，3} $进行了弦乐理论，其整体系数与$ζ（3）$成正比，并证明它与$ O（9,9,9）$ sommetry兼容。这证实了弦理论的一般结果，由于SEN，具有$ d $二维翻译不变性的经典字符串理论承认$ O（d，d）$对称$α'$。
We compute the cosmological reduction of the fourth powers of the Riemann tensor claimed to arise in string theory at order $α'^{\,3}$, with overall coefficient proportional to $ζ(3)$, and show that it is compatible with an $O(9,9)$ symmetry. This confirms the general result in string theory, due to Sen, that classical string theory with $d$-dimensional translation invariance admits an $O(d,d)$ symmetry to all orders in $α'$.
