带非局部竞争项的谱形最优化问题

A spectral shape optimization problem with a nonlocal competing term

Dario Mazzoleni, Berardo Ruffini

摘要:

我们研究了谱泛函的极小化问题,该谱泛函是Dirichlet Laplacian的第一特征值与Riesz型相互作用泛函的相对强度之和。我们证明了当Riesz排斥强度低于一个临界值时,极小值的存在性。然后,我们证明,通过一个扩展分析,球是一个刚性极小时,Riesz排斥足够小。最终,我们表明,某些制度的Riesz排斥,定期极小不存在。

英文摘要:

We study the minimization of a spectral functional made as the sum of the first eigenvalue of the Dirichlet Laplacian and the relative strength of a Riesz-type interaction functional. We show that when the Riesz repulsion strength is below a critical value, existence of minimizers occurs. Then we prove, by means of an expansion analysis, that the ball is a rigid minimizer when the Riesz repulsion is small enough. Eventually we show that for certain regimes of the Riesz repulsion, regular minimizers do not exist.
