$C^{1,α}$接口传输问题正则性的简单证明

A simple proof of regularity for $C^{1,α}$ interface transmission problems

Hongjie Dong

摘要:

本文给出了Caffarelli,Soria-Carro和Stinga在[1]中关于具有$C^{1,α}$界面的传输问题弱解的$C^{1,α}$正则性的一个结果的简单证明.我们的证明不使用平均值性质或最大值原理,也适用于更一般的椭圆系统。还讨论了对$C^{1,\text{Dini}}$接口和具有多个子域的域的一些扩展。

英文摘要:

We give a simple proof of a recent result in [1] by Caffarelli, Soria-Carro, and Stinga about the $C^{1,α}$ regularity of weak solutions to transmission problems with $C^{1,α}$ interfaces. Our proof does not use the mean value property or the maximum principle, and also works for more general elliptic systems. Some extensions to $C^{1,\text{Dini}}$ interfaces and to domains with multiple sub-domains are also discussed.
