Abstract: Two virtual link diagrams are homotopic if one may be transformed into theother by a sequence of virtual Reidemeister moves, classical Reidemeistermoves, and self crossing changes. We recall the pure virtual braid group. Wethen describe the set of pure virtual braids that are homotopic to the identitybraid.
