Query: Whitney towers and abelian invariants of knots   We relate certain abelian invariants of a knot, namely the Alexander
polynomial, the Blanchfield form, and the Arf invariant, to intersection data
of a Whitney tower in the 4-ball bounded by the knot. We also give a new
3-dimensional algorithm for computing these invariants.
