A new classification of links and some calculations using it
Colin Rourke, Brian J. Sanderson · arXiv (Cornell University) · 2000
A new classification theorem for links by the authors and Roger Fenn leads to computable link invariants. As an illustration we distinguish the left and right trefoils and recover the result of Carter et al that the 2-twist-spun trefoil is not isotopic to its orientation reverse. We sketch the proof the classification theorem. Full details will appear elsewhere
