图的余压缩与直角Artin群

Co-contractions of Graphs and Right-angled Artin Groups

Sang-hyun Kim

摘要:

我们在有限图上定义了一个操作,称为共同收缩。通过证明一个图的共同收缩诱导直角Artin群之间的内射映射,我们展示了一族图,没有任何长度至少为5的诱导圈,使得这些图上的直角Artin群包含双曲曲面群。这对Gordon、Long和Reid提出的一个问题给出了否定的答案。

英文摘要:

We define an operation on finite graphs, called co-contraction. By showing that co-contraction of a graph induces an injective map between right-angled Artin groups, we exhibit a family of graphs, without any induced cycle of length at least 5, such that the right-angled Artin groups on those graphs contain hyperbolic surface groups. This gives the negative answer to a question raised by Gordon, Long and Reid.
