UNLINKING NUMBER AND UNLINKING GAP [PDF]
Journal of Knot Theory and Its Ramifications, 2007 Computing unlinking number is usually very difficult and complex problem, therefore we define BJ-unlinking number and recall Bernhard–Jablan conjecture stating that the classical unknotting/unlinking number is equal to the BJ-unlinking number. We compute BJ-unlinking number for various families of knots and links for which the unlinking number is ...
