Ribbon Knot
If the Knot 
is the boundary 
of a singular disk 
which has theproperty that each self-intersecting component is an arc 
for which 
consists oftwo arcs in 
, one of which is interior, then is said to be a ribbon knot. Every ribbon knot is aSlice Knot, and it is conjectured that every Slice Knot is a ribbon knot.
