From Trees to Tripods: Proof of $K (π, 1)$ for Artin groups with $A B I$ -type spherical parabolics

Nima Hoda, Jingyin Huang

We reduce the $K (π, 1)$ -conjecture for all Artin groups with tree Coxeter diagrams to properties of Artin groups with tripod-shaped Coxeter diagrams. Combining this reduction theore…

Bestvina metric and tree reduction for $K (π, 1)$ -conjecture

Jingyin Huang

We reduce the $K (π, 1)$ -conjecture for all Artin groups to properties of Artin groups whose Coxeter diagrams are trees, from which we deduce new classes of Artin groups satisfying t…
