Multi-switches and virtual knot invariants
Abstract
In the paper we introduce a general approach how for a given virtual biquandle multi-switch (S,V) on an algebraic system X (from some category) and a given virtual link L construct an algebraic system XS,V(L) (from the same category) which is an invariant of L. As a corollary we introduce a new quandle invariant for virtual links which generalizes previously known quandle invariants for virtual links.
