The normalized version of the Alexander polynomial (cf. also Alexander invariants). It satisfies the Conway skein relation (cf. also Conway skein triple)

and the initial condition , where is the trivial knot (cf. also Knot theory). For one gets the original Alexander polynomial (defined only up to ).
