摘要

我们研究了在一个 7 维流形的定向超曲面上诱导出的近乎平行 G2 结构的 SU(3)- 结构。这种 SU(3) 结构被称为近半平面结构。我们描述了 S3×S3 上的左不变近半平面结构。这一特征有助于我们系统地分析S3×S3间隔上的近平行G2结构。

Nearly half-flat SU(3) structures on S3 × S3

We study the SU(3)-structure induced on an oriented hypersurface of a 7-dimensional manifold with a nearly parallel G2-structure. Such SU(3)-structures are called nearly half-flat. We characterise the left invariant nearly half-flat structures on S3×S3. This characterisation then helps us to systematically analyse nearly parallel G2-structures on an interval times S3×S3.
