Witryna3 kwi 2024 · There exist nontrivial ribbon knots in S 3, in particular, you cannot remove their double intersections. In particular, there are knots which bound immersed disks with double self-intersections, which do not bound embedded disks. Every ribbon knot bounds a smooth embedded disk in B 4, the unit 4-ball. In other words, every ribbon knot is … Witryna3 kwi 2024 · The immersed disk generically will have two kind of singularities, double points and triple points. The double points will be closed curves while the triple points a finite number of points. 1) What is an example when K bounds an immersed disk but not an embedded one? 2) Can we remove the double point singularities?
