摘要:

在SL(5)例外场论(ExFT)的背景下,我们构造了开闭弦映射的$d=11$超引力模拟.变形参数三向量$Ω$推广了开弦的非对易性双向量参数$Θ$。当应用于$d=11$中的解时,该映射提供了执行TsT变形的经济方式,并且可以用于在降维之后恢复$d=10$ Yang-Baxter变形。我们给出了经典Yang-Baxter方程(CYBE)在秩为3的天体上的推广,它源于$d=11$超引力和SL(5)ExFT.该方程被证明是减少到$d=10$ CYBE后降维。

英文摘要:

We construct a $d=11$ supergravity analogue of the open-closed string map in the context of SL(5) Exceptional Field Theory (ExFT). The deformation parameter tri-vector $Ω$ generalizes the non-commutativity bi-vector parameter $Θ$ of the open string. When applied to solutions in $d=11$, this map provides an economical way of performing TsT deformations, and may be used to recover $d=10$ Yang-Baxter deformations after dimensional reduction. We present a generalization of the Classical Yang-Baxter Equation (CYBE) for rank 3 objects, which emerges from $d=11$ supergravity and the SL(5) ExFT. This equation is shown to reduce to the $d=10$ CYBE upon dimensional reduction.
