Liftable automorphisms of right-angled Artin groups
Sangrok Oh, Donggyun Seo, Philippe Tranchida
Given a regular covering map of graphs, we investigate the subgroup of the automorphism group of the right-angled Arti…

Automorphism and outer automorphism groups of Right-angled Artin groups are not relatively hyperbolic
Junseok Kim, Sangrok Oh, Philippe Tranchida
We show that the automorphism groups of right-angled Artin groups whose defining graphs have at least 3 vertices are not relatively hyperbolic. We then show that the outer automorp…

Quasi-isometry invariants of weakly special square complexes
Sangrok Oh
We define the intersection complex for the universal cover of a compact weakly special square complex and show that it is a quasi-isometry invariant. By using this quasi-isometry i…
