Abstract.
We show that for \(n \geq 2\) all links of embedded n-spheres in \(S^{n+2}\) are singular slice, i.e. bound pairwise disjoint (but not embedded) n+1-disks in \(D^{n+3}\). The proof relies on a careful analysis of immersions in codimension two, that allows us to work in a nilpotent setting.
