Conjecture   Given a knot in $ S^3 $ which is slice, is it a ribbon knot?

The definitions of slice and ribbon: slice knot ribbon knot

There is a fairly vast literature on this problem. It is closely related to the problem of determining which homology $ 3 $-spheres bound homology $ 4 $-balls, as both are in essence a type of $ 4 $-dimensional cobordism problem.
