Query: Homology of subgroups of right-angled Artin groups   We describe the (co)homology of a certain family of normal subgroups of
right-angled Artin groups that contain the commutator subgroup, as modules over
the quotient group. We do so in terms of (skew) commutative algebra of
squarefree monomial ideals.
