d=11超引力中的非阿贝尔三矢量形变

Non-abelian tri-vector deformations in d=11 supergravity

Ilya Bakhmatov, Kirill Gubarev, Edvard T. Musaev

摘要:

构造了SL(5)例外场论的一个截断形式,它允许描述$M_4 \times M_7$形式的时空,在$M_4$上有4-形式通量.由此产生的理论是用来测试最近提出的三矢量推广的杨巴克斯特变形应用到AdS ${}_4 \times \mathbb{S}^7$解决方案在$d=11$超重力。给出了AdS ${}_4 \times \mathbb{S}^7$的非交换非么模三矢量形变的两个新的超引力解.

英文摘要:

A truncation of the SL(5) Exceptional Field Theory that allows to describe spacetimes of the form $M_4 \times M_7$ with the 4-form flux on $M_4$ is constructed. The resulting theory is used to test the recently proposed tri-vector generalisation of Yang-Baxter deformations applied to the AdS${}_4 \times \mathbb{S}^7$ solution in $d=11$ supergravity. We present two new supergravity solutions corresponding to non-abelian non-unimodular tri-vector deformations of AdS${}_4 \times \mathbb{S}^7$.
