Conway Polynomial


The Conway polynomial del _L(x), sometimes known as the Conway-Alexander polynomial, is a modified version of the Alexander polynomial Delta_L(x) that was formulated by J. H. Conway (Livingston 1993, pp. 207-215). It is a reparametrization of the Alexander polynomial given by

 Delta_L(x^2)=del _L(x-x^(-1)).

The skein relationship convention used by for the Conway polynomial is

 del _(L_+)(x)-del _(L_-)(x)=xdel _(L_0)(x)

(Doll and Hoste 1991).

Examples of Alexander Delta and Conway del polynomials for common knots are given in the following table
