[Title] Right-angled Artin groups and their automorphism groups
[Discipline] Group Theory
[Abstract]Right-angled Artin groups are fascinating objects in geometric topology and geometric group theory. They play a central role in Ian Agol’s proof of Thurston’s virtual fibering and virtual Haken conjectures, providing numerous examples in the field of geometric group theory. In this talk, we will focus on their automorphism groups and outer automorphism groups. I will introduce these groups from a group-theoretic perspective, covering aspects such as finite generation and the standard representation. If time permits, we will also explore the relationship between Gromov-hyperbolicity and the outer automorphism groups.
