Abstract: Let [Formula: see text] be ribbon knottings of [Formula: see text]-spheres or tori in [Formula: see text], [Formula: see text]. We show that if the knot quandles of these knots are isomorphic, then the ribbon… read more here.

Abstract: Suciu constructed infinitely many ribbon 2-knots in S4 whose knot groups are isomorphic to the trefoil knot group. They are distinguished by the second homotopy groups. We classify these knots by u... read more here.
