Query: Equivariant chain complexes, twisted homology and relative minimality of
  arrangements   We show that the equivariant chain complex associated to a minimal
CW-structure X on the complement M(A) of a hyperplane arrangement A, is
independent of X.
  When A is a sufficiently general linear section of an aspheric arrangement,
we explain a new way for computing the twisted homology of M(A).
