Seifert曲面的协调性

Concordance of Seifert surfaces

Robert Myers

摘要:

本文证明了$S^3$中纽结$K$的每一个定向非圆盘Seifert曲面$F$与任意大体积双曲纽结$K^{\prime}$的Seifert曲面$F^{\prime}$光滑协调.这给出了一个新的和更简单的证明结果弗里德尔和川内,每一个结是$S$ -相当于一个双曲结的任意大的体积。该结构也给出了一个新的和简单的证明结果银和Whitten和川内,对于每一个结$K$有一个双曲结$K^{\prime}$的任意大的体积和映射对$f:(S^3,K^{\prime})\rightarrow (S^3,K)$诱导满射的纽结群。文中给出一个例子,说明纽结弗洛尔同调不是塞弗特曲面协调的不变量。本文还证明了具有无界Haken数的有限体积双曲3-流形的体积是无界的。

英文摘要:

This paper proves that every oriented non-disk Seifert surface $F$ for a knot $K$ in $S^3$ is smoothly concordant to a Seifert surface $F^{\prime}$ for a hyperbolic knot $K^{\prime}$ of arbitrarily large volume. This gives a new and simpler proof of the result of Friedl and of Kawauchi that every knot is $S$-equivalent to a hyperbolic knot of arbitrarily large volume. The construction also gives a new and simpler proof of the result of Silver and Whitten and of Kawauchi that for every knot $K$ there is a hyperbolic knot $K^{\prime}$ of arbitrarily large volume and a map of pairs $f:(S^3,K^{\prime})\rightarrow (S^3,K)$ which induces an epimorphism on the knot groups. An example is given which shows that knot Floer homology is not an invariant of Seifert surface concordance. The paper also proves that a set of finite volume hyperbolic 3-manifolds with unbounded Haken numbers has unbounded volumes.
