Alexander多项式的次数是拓扑片亏格的一个上界

The degree of the Alexander polynomial is an upper bound for the topological slice genus

Peter Feller

摘要:

我们使用著名的结理论的弗里德曼的圆盘定理的结论-平凡的亚历山大多项式的结限制在4-球的局部平坦的圆盘-证明以下推广。纽结的Alexander多项式的次数是其拓扑片亏格的两倍的上界。我们提供的例子结,这决定了拓扑片属。

英文摘要:

We use the famous knot-theoretic consequence of Freedman's disc theorem---knots with trivial Alexander polynomial bound a locally-flat disc in the 4-ball---to prove the following generalization. The degree of the Alexander polynomial of a knot is an upper bound for twice its topological slice genus. We provide examples of knots where this determines the topological slice genus.
