From algebraic orthogonality to RAAG embedding obstructions in hierarchically hyperbolic groups
Sangrok Oh, Jihoon Park
We introduce the , which records minimal unbounded domains and their axial directions, for two classes of hierarchically hyperbolic group structures m…

Embeddability of right-angled Artin groups into hierarchically hyperbolic groups
Sangrok Oh, Jihoon Park
For a hierarchically hyperbolic group, we give sufficient conditions ensuring that suitable powers of a finite collection of elements generate a right-angled Artin subgroup; under…
