Abstract
This paper is concerned with the problem of when a Seifert surface for a slice knot can be 2-surgered to a disk in B 4. Techniques of 3-dimensional topology are the principal tools employed. The main theorem asserts that such a Seifert surface, F, can be 2-surgered to a disk in B 4 along a ribbon link if and only if there is a ribbon disk, Δ, spanning ∂ F such that the singular set of Δ misses the interior of F.
