在这些笔记中,我们介绍了具有 G × G 结构的空间概念及其结构化子流形。这些对象概括了校准子流形的经典概念。因此,从弦理论的角度来看,它们很有趣,因为它们与描述具有通量的背景下弦紧化中的 D 膜相关。本文基于第一作者在 RTN 研讨会“宇宙的构成、基本力和对称性”上的演讲,意大利那不勒斯,2006 年 10 月 9 日至 13 日。
In these notes we give an introduction to the concept of spaces with G × G‐structure and their structured submanifolds. These objects generalise the classical notion of a calibrated submanifold. Therefore, they are interesting from a string theory viewpoint as they are relevant to describe D‐branes in string compactifications on backgrounds with fluxes. This article is based on a talk given by the first author at the RTN Workshop “Constituents, Fundamental Forces and Symmetries of the Universe”, Naples, Italy, 9–13 Oct 2006.
