关于$\mathbb{Z}$ -亏格一致性的注记

A note on the concordance $\mathbb{Z}$-genus

Allison N. Miller, JungHwan Park

摘要:

我们发现,拓扑4-亏格的结和最小的曲面的亏格属的结,可以分解成一个光滑的和谐,其次是代数简单的局部平坦的表面可以是任意大的。这扩展了Hedden-Livingston-Ruberman的工作,证明了拓扑切片结与任何平凡的Alexander多项式结都不光滑一致。

英文摘要:

We show that the difference between the topological 4-genus of a knot and the minimal genus of a surface bounded by that knot that can be decomposed into a smooth concordance followed by an algebraically simple locally flat surface can be arbitrarily large. This extends work of Hedden-Livingston-Ruberman showing that there are topologically slice knots which are not smoothly concordant to any knot with trivial Alexander polynomial.
