Kleinian 4-群上正则格的上同调
Cohomologies of regular lattices over the Kleinian 4-group
摘要:
我们明确地计算了Kleinian 4-群上属于Auslander-Reiten群正则分支的格及其对偶模的上同调。结果被应用到一些晶体学和Chernikov群的分类。
英文摘要:
We calculate explicitly cohomologies of the lattices over the Kleinian 4-group belonging to the regular components of the Auslander-Reiten quiver as well as of their dual modules. The result is applied to the classification of some crystallographic and Chernikov groups.
