关于不含曲面子群的直角Artin群

On right-angled Artin groups without surface subgroups

Sang-hyun Kim

摘要:

本文研究了N类图,即不含曲面子群的直角Artin群。我们证明了一个可能更小的类N'是封闭的合并下沿完全子图,也下添加双单边。由此得出弦图和弦二部图属于N '。

英文摘要:

We study the class N of graphs, the right-angled Artin groups defined on which do not contain surface subgroups. We prove that a presumably smaller class N' is closed under amalgamating along complete subgraphs, and also under adding bisimplicial edges. It follows that chordal graphs and chordal bipartite graphs belong to N'.
