它表明,康威多项式的链接是一个产品的两个因素,其中第一个是康威多项式的结通过捆绑在一起的链接组件和第二个是确定的,通过一个明确的公式,由不变量的链接。特别地,我们得到了Conway多项式的第一个非零系数的μ-不变量公式。对于多元亚历山大多项式也得到了类似的公式。
It is shown that the Conway polynomial of a link is a product of two factors, the first of which is the Conway polynomial of a knot obtained by banding together the link components and the second is determined, via an explicit formula, by the-invariants of the link. In particular we get a formula, in terms of the μ-invariants, for the first non-zero coefficient of the Conway polynomial. A similar formula is obtained for the multi-variable Alexander-polynomial.
