Abstract
We provide obstructions to a link in S³ arising as the cross section of any number of unlinked spheres in S⁴. Our obstructions arise from the multivariable signature, the Blanchfield form and generalised Seifert matrices. We also obtain obstructions in the case of surfaces of higher genera, leading to a lower bound on the doubly slice genus of links. Show more
