超弦可积性的Chern-Simons起源

The Chern-Simons Origin of Superstring Integrability

Kevin Costello, Bogdan Stefański

摘要:

我们从四维Beltrami-Chern-Simons理论中导出了AdS ${}_5\times$ S ${}^5$ Green-Schwarz超弦.在这种构造中,可积超弦的Lax联络和谱参数在四维空间中有一个简单的几何原点作为规范联络和约化坐标。Kappa对称性产生于一类奇异规范变换,而世界表度规则来自于复杂的结构变化的贝尔特拉米微分。我们的方法提供了使用传统的场论方法研究可积全息的可能性。

英文摘要:

We derive the AdS${}_5\times$S${}^5$ Green-Schwarz superstring from four-dimensional Beltrami-Chern-Simons theory reduced on a manifold with singular boundary conditions. In this construction, the Lax connection and spectral parameter of the integrable superstring have a simple geometric origin in four dimensions as gauge connection and reduction coordinate. Kappa symmetry arises as a certain class of singular gauge transformations, while the worldsheet metric comes from complex-structure-changing Beltrami differentials. Our approach offers the possibility of investigating integrable holography using traditional field theory methods.
