AI总结:

本文研究吸引域收缩的竞争型弱耦合椭圆薛定谔系统,证明无穷多解与非负最小能量解的存在性,分析解的集中行为与极限形态,揭示分量吸引区域异同对极限下耦合性的影响。

摘要:

本文研究一类竞争型弱耦合椭圆系统,其中每个物种都被一个小区域吸引,且受到该区域补集的排斥。在此设定下,我们证明了系统存在无穷多解,以及一个非负的最小能量解。我们表明,当吸引域收缩时,系统的最小能量解会发生集中现象。我们研究了这一行为,并刻画了它们的极限形态。特别地,我们证明:若最小能量解的每个分量都被不同的区域吸引,则各分量在极限下解耦;而若所有分量都被同一个区域吸引,则它们保持耦合。

英文摘要:

In this paper we consider a competitive weakly coupled elliptic system in which each species is attracted to a small region and repelled from its complement. In this setting, we establish the existence of infinitely many solutions and of a nonnegative least energy solution. We show that, as the regions of attraction shrink, least energy solutions of the system concentrate. We study this behavior and characterize their limit profile. In particular, we show that if each component of a least energy solution is attracted to a different region, then the components decouple in the limit, whereas if all the components are attracted to the same region, they remain coupled.
