A note on nilpotent subgroups of automorphism groups of RAAGs. (arXiv:1803.08284v1 [math.GR])
来源于:arXiv
We observe that automorphism groups of right-angled Artin groups contain
nilpotent non-abelian subgroups, namely $H_3(\mathbb{Z})$ the three-dimensional
integer Heisenberg group, provided they admit a certain type of element, called
an adjacent transvection. This represents a (minor) extension of a result of
Charney-Vogtmann. 查看全文>>
