Query: Concordance of links with identical Alexander invariants   J. Davis showed that the topological concordance class of a link in the
3-sphere is uniquely determined by its Alexander polynomial for 2-component
links with Alexander polynomial one. A similar result for knots with Alexander
polynomial one was shown earlier by M. Freedman. We prove that these two cases
are the only exceptional cases, by showing that the link concordance class is
not determined by the Alexander invariants in any other case.
