Fully classifying virtual string links up to cobordisms
by
Robin Gaudreau
University of Toronto

Virtual string links are oriented tangles with classical and virtual crossings, and such that the endpoints can be grouped into two connected sets, one outgoing and one incoming. While classical knots can all be unknotted using cobordisms, cobordisms classes of virtual string links on n components form a non-trivial free abelian group.
