泊松-李对偶性提供了弦理论的传统阿贝尔和非阿贝尔目标空间对偶性的代数扩展,并且最近在构造全息术的量子群变形中得到了应用。在这里,我们使用例外场论工具展示了泊松李到 M 理论背景的自然升级。特别是,我们提出了如何将德林菲尔德双精度数的基本思想推广到我们称为特殊德林菲尔德代数的代数。这些承认“最大各向同性子代数”的概念,并且我们展示了如何定义此类子代数的相关群流形上的广义 Scherk-Schwarz 截断。这使我们能够定义泊松李 U 对偶性的概念。此外,例外的德林菲尔德代数的闭包条件定义了德林菲尔德双数中出现的余循环和余雅可比条件的自然类似物。我们证明,在对余循环进行进一步的共界限制时,会出现杨-巴克斯特变形的 M 理论扩展。我们评论这种结构作为超重力内的解决方案生成技术的应用。
Poisson-Lie duality provides an algebraic extension of conventional Abelian and non-Abelian target space dualities of string theory and has seen recent applications in constructing quantum group deformations of holography. Here we demonstrate a natural upgrading of Poisson-Lie to the context of M-theory using the tools of exceptional field theory. In particular, we propose how the underlying idea of a Drinfeld double can be generalised to an algebra we call an exceptional Drinfeld algebra. These admit a notion of “maximally isotropic subalgebras” and we show how to define a generalised Scherk-Schwarz truncation on the associated group manifold to such a subalgebra. This allows us to define a notion of Poisson-Lie U-duality. Moreover, the closure conditions of the exceptional Drinfeld algebra define natural analogues of the cocycle and co-Jacobi conditions arising in Drinfeld double. We show that upon making a further coboundary restriction to the cocycle that an M-theoretic extension of Yang-Baxter deformations arise. We remark on the application of this construction as a solution-generating technique within supergravity.
