- the cohomology with group ring coefficients of Artin groups (or actually, of their associated Salvetti complexes), of Bestvina–Brady groups of type FP, and of graph products of groups,
- the -Betti numbers of Bestvina–Brady groups of type FP over , and of graph products of groups,
- the weighted -Betti numbers of graph products of Coxeter groups.
In the case of arbitrary graph products there is an additional proviso: either all factors are infinite or all are finite.
