AI总结:

本文证明三维球面中两分支链环的Möbius交叉能量临界值$2\pi^2$是孤立的,即能量接近该值的非分裂正则曲线对必为Hopf链环的Möbius轨道。

AI中文摘要:

我们证明了在三维球面$\mathbb{S}^{3}$中,两分支链环的Möbius交叉能量的临界值$2\pi^2$是孤立的。具体而言,存在$\varepsilon_0>0$,使得任何非分裂、正则的$H^2$曲线对,若其像不相交、具有消失的一阶变分且能量至多为$2\pi^2+\varepsilon_0$,则必须位于标准Hopf链环的Möbius重参数化轨道中。

英文摘要:

We prove that the critical value $2π^2$ is isolated for the Möbius cross energy of two-component links in the round three dimensional sphere $\mathbb{S}^{3}$. Specifically, there exists $\varepsilon_0>0$ such that any non-split, regular $H^2$ pair of curves with disjoint images, having vanishing first variation and energy at most $2π^2+\varepsilon_0$, must lie in the Möbius-reparametrization orbit of the standard Hopf link.
