Abstract

A link in the 3–sphere is called (smoothly) slice if its components bound disjoint smoothly embedded disks in the 4–ball. More generally, given a 4–manifold M with a distinguished circle in its boundary, a link in the 3–sphere is called M–slice if its components bound in the 4–ball disjoint embedded copies of M. A 4–manifold M is constructed such that the Borromean rings are not M–slice but the Hopf link is. This contrasts the classical link-slice setting where the Hopf link may be thought of as “the most nonslice” link. Further examples and an obstruction for a family of decompositions of the 4–ball are discussed in the context of the A-B slice problem.
