论文摘要
我们表明，在$ t^4 $上压实的NS5-溴化物的接近摩尼子解耦区域中产生的三维渐近线性diLATON背景允许导致无限对称性的边界条件。相关的保守电荷（实现了磁场依赖的坐标转换）被发现与$ t \ bar t $ - 变形的CFT中的对称产物中的相应发电机相同。他们的代数是对$ \ mathrm {virasoro \ times virasoro} $代数的非线性修改，它与$ t \ bar t $ defformed cfts中的“未估计”对称发生器的代数相吻合。这进一步加强了先前提出的单个跟踪$ t \ bar t $变形与压缩小字符串理论之间的联系。
We show that the three-dimensional asymptotically linear dilaton background that arises in the near-horizon decoupling region of NS5-branes compactified on $T^4$ admits boundary conditions that lead to an infinite set of symmetries. The associated conserved charges, which implement field-dependent coordinate transformations, are found to be identical to the corresponding generators in a symmetric product orbifold of $T\bar T$ - deformed CFTs. Their algebra is a non-linear modification of the $\mathrm{Virasoro \times Virasoro}$ algebra, which precisely coincides with the algebra of the "unrescaled" symmetry generators in $T\bar T$-deformed CFTs. This further strengthens a previously proposed link between the single-trace $T\bar T$ deformation and compactified little string theory.
