一般形式的非局部能量极小化测度的存在性和有界性

On the existence and boundedness of minimizing measures for a general form of non-local energies

Davide Carazzato, Aldo Pratelli

摘要:

在本文中,我们考虑一个非常普遍的形式的非局部能量的积分形式,它涵盖了大多数常见的(例如,一个积极的和一个消极的权力)。而不是只承认集,或$L^\infty$功能,作为可接受的对象,我们定义的能量为所有的氡措施。我们证明了存在的最佳措施,在广泛的一般性,我们表明,在几种情况下,最佳措施实际上是$L^\infty$功能,提供了一个先验的约束其规范。我们还得到了一个唯一性结果的极小。

英文摘要:

In this paper we consider a very general form of a non-local energy in integral form, which covers most of the usual ones (for instance, the sum of a positive and a negative power). Instead of admitting only sets, or $L^\infty$ functions, as admissible objects, we define the energy for all the Radon measures. We prove the existence of optimal measures in a wide generality, and we show that in several cases the optimal measures are actually $L^\infty$ functions, providing an a priori bound on their norm. We also derive a uniqueness result for minimizers.
