We consider equivalence classes of 3-coloured knots and of 5-coloured knots under colour -preserving Dehn surgery. We show that the equivalence cla...

As the title says, we prove that a certain space of diagrams vanishes. This shows that there are no Vassiliev invariants (finite type invariants) w...
