Large‐type Artin groups are systolic

We prove that Artin groups from a class containing all large‐type Artin groups are systolic. This provides a concise yet precise description of their geometry. Immediate consequences are new results concerning large‐type Artin groups: biautomaticity; existence of EZ‐boundaries; the Novikov conjectur...

description We prove that Artin groups from a class containing all large‐type Artin groups are systolic. This provides a concise yet precise description of their geometry. Immediate consequences are new results concerning large‐type Artin groups: biautomaticity; existence of EZ‐boundaries; the Novikov conjecture; descriptions of finitely presented subgroups, of virtually solvable subgroups, and of centralizers of elements; the Burghelea conjecture; existence of low‐dimensional models for classifying spaces for some families of subgroups.
