经典的 Stmapacchia 引理在椭圆型偏微分方程的正则性理论和变分问题中有广泛应用.本文总结 Stampacchia 引理和此引理的若干推广,并给出这些推广在某退缩椭圆型偏微分方程正则性理论中的应用.
The classical Stampacchia lemma has been widely used in the regularity theory of elliptic partial differential equations and systems as well as variational problems. This paper summarizes the Stampacchia lemma and their generalizations, and give an application to the regularity theory of degenerate elliptic partial differential equations.
