纽结稳定4-亏格的一个下界

A lower bound on the stable 4-genus of knots

Damian Iltgen

摘要:

基于Casson-Gordon $τ$ -签名,给出了纽结的稳定$4$ -亏格的下界.我们计算的下界为一个无限的家庭的结,扭结,并表明,扭结是扭的结和谐组的当且仅当它有消失的稳定$4$ -属。

英文摘要:

We present a lower bound on the stable $4$-genus of a knot based on Casson-Gordon $τ$-signatures. We compute the lower bound for an infinite family of knots, the twist knots, and show that a twist knot is torsion in the knot concordance group if and only if it has vanishing stable $4$-genus.
