本文介绍了二桥纽结的扩展图,并说明了如何从该图直接读出纽结的亚历山大多项式的系数。使用这个结果,它是由图表操作表明,福克斯的猜想的系数的亚历山大多项式的交替结是真实的,至少对两个桥接的结(这是所有交替)。1980年数学学科分类(美国数学学会):57米25。
Abstract The extended diagram of a two-bridged knot is introduced, and it is shown how the coefficients of the Alexander polynomial of the knot may be read straight from this diagram. Using this result, it is shown by diagram manipulation that a conjecture of Fox about the coefficients of the Alexander polynomial of an alternating knot is true at least for two-bridged knots (which are all alternating). 1980 Mathematics subject classification (Amer. Math. Soc.): 57 M 25.
