Quasi-projectivity of even Artin groups

Rubén Blasco-García and José Ignacio Cogolludo-Agustín

Geometry & Topology 22 (2018) 3979–4011
Abstract

Even Artin groups generalize right-angled Artin groups by allowing the labels in the defining graph to be even. We give a complete characterization of quasi-projective even Artin groups in terms of their defining graphs. Also, we show that quasi-projective even Artin groups are realizable by K(π,1) quasi-projective spaces.

Keywords
