Suciu's ribbon 2-knots with isomorphic group

Taizo Kanenobu, Toshio Sumi

Research output: Contribution to journalArticlepeer-review


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 using SL(2,)-representations of the fundamental groups of the 2-fold branched covering spaces.
