论文摘要
本文对封闭的G2结构进行了分类,以使诱导的度量标准在形式上是平坦的。结果表明,任何具有共形平面度量的封闭的G2结构在局部等同于三个显式示例之一。特别是,从分类中遵循的任何封闭的G2结构诱导了既平面又完整的度量标准,都必须等于$ \ Mathbb {r}^7的平面G2结构。
This article classifies closed G2-structures such that the induced metric is conformally flat. It is shown that any closed G2-structure with conformally flat metric is locally equivalent to one of three explicit examples. In particular, it follows from the classification that any closed G2-structure inducing a metric that is both conformally flat and complete must be equivalent to the flat G2-structure on $\mathbb{R}^7.$
