A POLYNOMIAL INVARIANT FOR FLAT VIRTUAL LINKS
A POLYNOMIAL INVARIANT FOR FLAT VIRTUAL LINKS
This paper gives a polynomial invariant for flat virtual links. In the case of one component, the polynomial specializes to Turaev's virtual string polynomial. We show that Turaev's polynomial has the property that it is non-zero precisely when there is no filamentation of the knot, as described by Hrencecin and …
