论文摘要
广义二元性在本地$ O（d，d）$转换方面引起了双场理论（DFT）的吸引人入侵。我们回顾了这一想法，并使用DFT的较高导数公式来计算一阶校正为广义二元性。我们的主要结果是统一的表达式，可以轻松地指定为任何一般的T偶对（Abelian，非阿贝尔，Poisson-lie等）或诸如Yang-Baxter之类的变形，在任何由Bi-Parametric变形（Bosonic，Obosonic，Orgotic Strings and Hsz Theory）捕获的任何理论中，在任何相关的超级Grancavity方案中都列于领域。该处方允许进一步扩展到更高的订单。作为检查，我们恢复了一些先前已知的特定示例。
Generalized dualities had an intriguing incursion into Double Field Theory (DFT) in terms of local $O(d,d)$ transformations. We review this idea and use the higher derivative formulation of DFT to compute the first order corrections to generalized dualities. Our main result is a unified expression that can be easily specified to any generalized T-duality (Abelian, non-Abelian, Poisson-Lie, etc.) or deformations such as Yang-Baxter, in any of the theories captured by the bi-parametric deformation (bosonic, heterotic strings and HSZ theory), in any supergravity scheme related by field redefinitions. The prescription allows further extensions to higher orders. As a check we recover some previously known particular examples.
