紧流形上的Hopf孤子

Hopf solitons on compact manifolds

R. S. Ward

摘要:

$R^3$上Skyrme-Faddeev系统中的Hopf孤子具有复杂的结构,特别是当Hopf数Q较大时.相比之下,如果我们在紧致的3-流形M上工作,并且能量泛函仅由Skyrme项(强耦合极限)组成,则图像简化。在能量上存在拓扑下界$E\geq Q$,并且即使对于大Q,E的局部最小值也可以看起来简单。这里的目的是描述和研究其中的一些解决方案,当M是$S^3$,$T^3$或$S^2 \times S^1$。此外,我们回顾了更基本的baby-Skyrme系统,M是$S^2$或$T^2$。

英文摘要:

Hopf solitons in the Skyrme-Faddeev system on $R^3$ typically have a complicated structure, in particular when the Hopf number Q is large. By contrast, if we work on a compact 3-manifold M, and the energy functional consists only of the Skyrme term (the strong-coupling limit), then the picture simplifies. There is a topological lower bound $E\geq Q$ on the energy, and the local minima of E can look simple even for large Q. The aim here is to describe and investigate some of these solutions, when M is $S^3$, $T^3$ or $S^2 \times S^1$. In addition, we review the more elementary baby-Skyrme system, with M being $S^2$ or $T^2$.
