论文摘要
我们在三维反DE保姆时空中构建弦理论，该时空独立于边界指标。这是拓扑扭曲的量子重力理论。我们研究具有渐近n = 2超符号对称性的弦理论，并证明，当世界纸耦合到时空边界耦合时，将经历u（1）r对称性扭曲时，时空边界的能量摩托张量就变成了拓扑。作为我们分析的副产品，我们获得了世界板顶点操作员，该操作员编码了时空能量摩托车，以进行共同平坦的边界指标。
We construct a string theory in three-dimensional anti-de Sitter space-time that is independent of the boundary metric. It is a topologically twisted theory of quantum gravity. We study string theories with an asymptotic N=2 superconformal symmetry and demonstrate that, when the world sheet coupling to the space-time boundary metric undergoes a U(1) R-symmetry twist, the space-time boundary energy-momentum tensor becomes topological. As a by-product of our analysis, we obtain the world sheet vertex operator that codes the space-time energy-momentum for conformally flat boundary metrics.
