VIRTUAL HOMOTOPY

open access: yesJournal of Knot Theory and Its Ramifications, 2010
Two welded (respectively virtual) link diagrams are homotopic if one may be transformed into the other by a sequence of extended Reidemeister moves, classical Reidemeister moves, and self crossing changes. In this paper, we extend Milnor's μ and [Formula: see text] invariants to welded and virtual links.
