无结构条件障碍问题的正则性

Regularity for Obstacle Problems without Structure Conditions

Giacomo Bertazzoni, Samuele Riccò

摘要:

本文研究一类可能出现Lavrentiev现象的变分障碍问题极小解的Lipschitz正则性。为了克服这个问题,需要利用松弛泛函和Lavrentiev间隙的概念。这里使用的主要工具是一个巧妙的引理,它显示是至关重要的,因为它允许我们从变分障碍问题的松弛功能相关的。这对于寻找我们所要研究的解的规律性是至关重要的。我们假设障碍物的梯度和系数都具有相同的Sobolev正则性。

英文摘要:

This paper deals with the Lipschitz regularity of minimizers for a class of variational obstacle problems with possible occurance of the Lavrentiev phenomenon. In order to overcome this problem, the availment of the notions of relaxed functional and Lavrentiev gap are needed. The main tool used here is a ingenious Lemma which reveals to be crucial because it allows us to move from the variational obstacle problem to the relaxed-functional-related one. This is fundamental in order to find the solutions' regularity that we intended to study. We assume the same Sobolev regularity both for the gradient of the obstacle and for the coefficients.
