In the 60's Levine proved that if RR is a slice knot, then on any genus gg Seifert surface for RR there is a gg component link JJ, called a derivative of RR, on which the Seifert form vanishes. Many subsequent obstructions to RR being slice are given in terms of slice obstructions of JJ. Many of these obstructi…
