在超重力中嵌入改进的CYBE

Embedding the modified CYBE in Supergravity

Thiago Araujo, Eoin Ó Colgáin, Hossein Yavartanoo

摘要:

最近的研究表明,经典杨-巴克斯特方程(CYBE)是通过开-闭弦映射从超引力中产生的。因此,给定任何具有等距群的解,存在基于齐次CYBE的$r$矩阵解的变形解。在这项工作中,我们认为,CYBE出现完全从NS部门,而RR部门的行为主要是作为一个旁观者,支持时空。此外,通过一个常数的移动,可以将$r$ -矩阵的解决方案,修改CYBE,但仅限于原来的几何是陪集空间的直积。我们说明了我们的解决方案生成技术与变形的$AdS_3 \times S^3 \times M_4$,其中$M_4 = T^4$(K3)和$S^3 \times S^1$,并明确地构建一个和两个参数(可积)的q-变形的解决方案,广义超引力。

英文摘要:

It has recently been demonstrated that the Classical Yang-Baxter Equation (CYBE) emerges from supergravity via the open-closed string map. Thus, given any solution with an isometry group, there exists a deformed solution based on an $r$-matrix solution to the homogeneous CYBE. In this work, we argue that the CYBE emerges exclusively from the NS sector, while the RR sector acts largely as a spectator that supports the spacetimes. Moreover, shifting the dilaton by a constant, one can incorporate $r$-matrix solutions to the modified CYBE, but only for original geometries that are a direct-product of coset spaces. We illustrate our solution generating technique with deformations of $AdS_3 \times S^3 \times M_4$, where $M_4 = T^4$ (K3) and $S^3 \times S^1$, and explicitly construct one and two-parameter (integrable) q-deformations that are solutions to generalised supergravity.
