本文分类了作为光滑复拟射影簇基本群的加权右角Artin群,证明它们恰为有限生成自由群与形如$\langle a,b\mid [a,b]^m=1\rangle$的群的有限直积。
AI 中文摘要
加权右角Artin群通过在定义图的边上添加权重来推广右角Artin群。我们分类了作为光滑复拟射影簇基本群出现的加权右角Artin群。它们恰好是有限生成自由群与形如$\langle a,b\mid [a,b]^m=1\rangle$的群的有限直积。
英文摘要
Weighted right-angled Artin groups generalize right-angled Artin groups by adding weights to the edges of the defining graphs. We classify the weighted right-angled Artin groups that occur as fundamental groups of smooth complex quasi-projective varieties. They are precisely the finite direct products of finitely generated free groups and groups of the form $\langle a,b\mid [a,b]^m=1\rangle$.
