我们研究非局部方程,其中,,是Riesz势,是一个小参数。我们表明,如果外部潜力有一个局部最小值,然后为所有小的问题有一个家庭的解决方案,集中到当地的最小值提供:要么,或,或和。我们对的衰减和的容许范围的假设是最优的。证明使用变分方法和一种新的非局部惩罚技术,我们在这项工作中开发。
We study the nonlocal equation where , , is the Riesz potential and is a small parameter. We show that if the external potential has a local minimum and then for all small the problem has a family of solutions concentrating to the local minimum of provided that: either , or and , or and . Our assumptions on the decay of and admissible range of are optimal. The proof uses variational methods and a novel nonlocal penalization technique that we develop in this work.
