The history of the geometry of Double Field Theory is the history of string theorists' effort to tame higher geometric structures. In this spirit, the first part of this paper will contain a brief overview on the literature of geometry of DFT, focusing on the attempts of a global description.

全局双场理论之谜：未解决的问题和 Kaluza-Klein 更高视角的案例

双场论几何学的历史就是弦理论家努力驯服更高几何结构的历史。本着这种精神，本文的第一部分将简要概述 DFT 几何的文献，重点是全局描述的尝试。
