质量输运不等式引起的自由边界问题的整体解

Global solutions of a free boundary problem via mass transport inequalities

Gioia Carinci, Anna De Masi, Cristian Giardina', Errico Presutti

摘要:

我们研究了一个自由边界问题,它是在傅立叶定律的背景下随机粒子系统的连续形式。经典解的局部存在唯一性在自由边界问题的文献中是众所周知的。我们引入了广义解的概念(当经典解存在时,它是经典解的推广),并证明了对于一大类初始数据,广义解的整体存在性和唯一性.证明是通过表征广义解的唯一元素,它分离适当定义的上下障碍的意义上的质量传输不等式。

英文摘要:

We study a free boundary problem which arises as the continuum version of a stochastic particles system in the context of Fourier law. Local existence and uniqueness of the classical solution are well known in the literature of free boundary problems. We introduce the notion of generalized solutions (which extends that of classical solutions when the latter exist) and prove global existence and uniqueness of generalized solutions for a large class of initial data. The proof is obtained by characterizing a generalized solution as the unique element which separates suitably defined lower and upper barriers in the sense of mass transport inequalities.
