A new classiication theorem for links by the authors and Roger Fenn leads to computable link invariants.

We sketch the proof the classiication theorem. Full details will appear elsewhere
Trefoil factors (TFF) are secretory products of mucin producing cells. They play a key role in the maintenance of the surface integrity of oral mucosa and enhance healing of the gastrointestinal mucosa by a process called restitution. TFF comprises the gastric peptides (TFF1), spasmolytic peptide (TFF2), and the intestinal trefoil factor (TFF3). They have an important and necessary role in epit...
