李群上ERP G2-structures的分类

The classification of ERP G2-structures on Lie groups

Jorge Lauret, Marina Nicolini

摘要:

在等价和标度的条件下,得到了极端Ricci压缩的李群上左不变闭G2-结构的完全分类.它们有五个,它们被定义在五个不同的完全可解的李群上,并且G2-结构在所有情况下都是精确的,除了一个,由唯一的例子给出,其中李群是幺模的。

英文摘要:

A complete classification of left-invariant closed G2-structures on Lie groups which are extremally Ricci pinched, up to equivalence and scaling, is obtained. There are five of them, they are defined on five different completely solvable Lie groups and the G2-structure is exact in all cases except one, given by the only example in which the Lie group is unimodular.
