Embeddability problem in right-angled Artin groups
[2017 KAIST Math. Colloquium]
Date: 2017-10-26
Speaker : 이언경 (세종대학교)
Abstract : Right-angled Artin groups (RAAGs) are defined from finite simplicial graphs. It is a fundamental question whether or not, given two RAAGs, there is an embedding from one group to the other. Extension graphs are useful in solving this problem. In this talk, I will briefly review RAAGs and extension graphs, and show some results on solving the embeddability problem in RAAGs by using extension graphs.
