经典Aubin-Lions引理的几个变形

Some variants of the classical Aubin-Lions Lemma

Ayman Moussa

摘要:

本文研究了经典Aubin-Lions引理的两个推广。首先给出两个函数的弱极限与乘法可交换的一个充分条件。我们从这个准则推出了退化抛物型方程的一个紧性定理。其次,我们陈述并证明了一个非圆柱型区域的紧性定理,包括仅包含无发散检验函数的对偶估计的情形。

英文摘要:

This paper explores two generalizations of the classical Aubin-Lions Lemma. First we give a sufficient condition to commute weak limit and multiplication of two functions. We deduce from this criteria a compactness Theorem for degenerate parabolic equations. Secondly, we state and prove a compactness Theorem for non-cylindrical domains, including the case of dual estimates involving only divergence-free test functions.
