五维连通Simply Connected幂零李群的离散余紧子群

Discrete Cocompact Subgroups of the Five-Dimensional Connected and Simply Connected Nilpotent Lie Groups

Amira Ghorbel, Hatem Hamrouni

摘要:

在同构的意义下,确定了五维连通、单连通幂零李群的离散余紧子群。证明了如果$G=N\times A$是一个连通、单连通、幂零的李群,且具有一个阿贝尔因子$A$,则$G$的每个一致子群都是$N$的一个一致子群与${\mathbb Z}^r$的直积,其中$r=\dim A$ .

英文摘要:

The discrete cocompact subgroups of the five-dimensional connected, simply connected nilpotent Lie groups are determined up to isomorphism. Moreover, we prove if $G=N\times A$ is a connected, simply connected, nilpotent Lie group with an Abelian factor $A$, then every uniform subgroup of $G$ is the direct product of a uniform subgroup of $N$ and ${\mathbb Z}^r$ where $r=\dim A$.
