Ribbon knot
In the mathematical area of knot theory, a ribbon knot is a knot that bounds a self-intersecting disk with only ribbon singularities. Intuitively, this kind of singularity can be formed by cutting a s
Slice knot
A slice knot is a mathematical knot in 3-dimensional space that bounds an embedded disk in 4-dimensional space.
