反de Sitter空间中的扭曲弦论

Twisted String Theory in Anti-de Sitter Space

Songyuan Li, Jan Troost

摘要:

我们在三维反德西特时空中构造了一个与边界度规无关的弦论。它是一种拓扑扭曲的量子引力理论。我们研究了具有渐近N=2超共形对称性的弦论,并证明了当耦合到时空边界度规的世界片经历U(1)R对称扭曲时,时空边界能量动量张量变成拓扑的。作为我们的分析的副产品,我们得到的世界片顶点运营商编码的时空能量动量共形平坦的边界度规。

英文摘要:

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.
