一致正则集上的非定域相互作用方程

Nonlocal-interaction equations on uniformly prox-regular sets

José A. Carrillo, Dejan Slepčev, Lijiang Wu

摘要:

研究了一般区域$Ω\subset \mathbb{R}^d$上一类非局部相互作用方程的适定性,包括非凸区域。我们证明了在对区域的正则性(一致正则性)的温和假设下,对于$λ$ -测地凸相互作用和外势,非定域相互作用方程存在唯一的弱测度解.此外,我们显示定量估计的稳定性的解决方案,量化的相互作用的几何结构的域和凸的能量。我们使用这些结果来调查哪些域和哪些潜在的解决方案聚合到一个单一的点,随着时间的推移到无穷大。我们的方法是基于概率测度空间中的梯度流理论。

英文摘要:

We study the well-posedness of a class of nonlocal-interaction equations on general domains $Ω\subset \mathbb{R}^d$, including nonconvex ones. We show that under mild assumptions on the regularity of domains (uniform prox-regularity), for $λ$-geodesically convex interaction and external potentials, the nonlocal-interaction equations have unique weak measure solutions. Moreover, we show quantitative estimates on the stability of solutions which quantify the interplay of the geometry of the domain and the convexity of the energy. We use these results to investigate on which domains and for which potentials the solutions aggregate to a single point as time goes to infinity. Our approach is based on the theory of gradient flows in spaces of probability measures.
