We generalize to certain families of even Artin groups several classical results on right-angled Artin groups. In particular, we compute the cohomology ring, describe the pro- c…

Actions with a strong fundamental domain and Sigma invariants of groups
Peio Ardaiz Galé, Marcos Escartín Ferrer, Conchita Martínez Perez
We show that if a group acts on a contractible -complex with a contractible strong fundamental domain and the stabilizers of the action satisfy certain properties, then the…
