  There are several topological spaces associated to a complex hyperplane
arrangement: the complement and its boundary manifold, as well as the Milnor
fiber and its own boundary. All these spaces are related in various ways,
primarily by a set of interlocking fibrations. We use cohomology with
coefficients in rank 1 local systems on the complement of the arrangement to
gain information on the homology of the other three spaces, and on the
monodromy operators of the various fibrations.
