Laura Abatangelo, Veronica Felli, Benedetta Noris

摘要:

本文研究了有界区域上具有齐次Dirichlet边界条件的限制分数拉普拉斯算子的本征值问题。我们引入了紧子集的分数容量的概念,其特征值不受去除零分数容量集的影响。给定一个简单的本征值,我们从域中删除一个家庭的紧凑集集中到一组零分数的能力,我们检测的本征值变化的渐近展开,这种扩展依赖于本征函数相关联的极限本征值。最后,我们研究了紧集族集中于一点的情形。

英文摘要:

We consider the eigenvalue problem for the restricted fractional Laplacian in a bounded domain with homogeneous Dirichlet boundary conditions. We introduce the notion of fractional capacity for compact subsets, with the property that the eigenvalues are not affected by the removal of zero fractional capacity sets. Given a simple eigenvalue, we remove from the domain a family of compact sets which are concentrating to a set of zero fractional capacity and we detect the asymptotic expansion of the eigenvalue variation; this expansion depends on the eigenfunction associated to the limit eigenvalue. Finally, we study the case in which the family of compact sets is concentrating to a point.
