相对论非阿贝尔Chern-Simons模型的双周期自对偶涡旋

Doubly Periodic Self-Dual Vortices for a Relativistic Non-Abelian Chern--Simons Model

Xiaosen Han, Gabriella Tarantello

摘要:

本文建立了一个关于$2\times2$非线性椭圆型方程组双周期解存在性的多重性结果。我们发现,给定的系统承认至少有两个解决方案时,陈-Simons耦合参数$κ>0$是足够小的,而没有解决方案存在$κ>0$足够大。在[36]中,我们使用问题的变分公式。因此,我们通过(局部)最小化方法获得第一个解决方案,并表明它是渐近规范等价的(破碎)主嵌入真空系统,作为$κ\to 0$。然后,我们得到了第二个解决方案的“山口”型的最小-最大程序。

英文摘要:

In this paper we establish a multiplicity result concerning the existence of doubly periodic solutions for a $2\times2$ nonlinear elliptic system arising in the study of self-dual non-Abelian Chern--Simons vortices. We show that the given system admits at least two solutions when the Chern--Simons coupling parameter $κ>0$ is sufficiently small; while no solutions exist for $κ>0$ sufficiently large. As in [36] we use a variational formulation of the problem. Thus, we obtain a first solution via a (local) minimization method and show that it is asymptotically gauge-equivalent to the (broken) principal embedding vacuum of the system, as $κ\to 0$. Then we obtain the second solution by a min-max procedure of "mountain pass" type.
