具有分段光滑系数的线性椭圆型方程组的分段光滑性

Piecewise smoothness for linear elliptic systems with piecewise smooth coefficients

Youchan Kim

摘要:

Li和Vogelius,Li和Nirenberg分别得到了复合材料中具有逐段$C^γ$ -系数的线性椭圆问题的逐段$C^{1,γ}$ -正则性.本文得到了具有分段$C^{m,γ}$ -系数的线性椭圆型方程组的分段$C^{m+1,γ}$ -正则性,该方程组也来自复合材料.这回答了李和Vogelius,李和尼伦伯格提出的开放性问题。

英文摘要:

Li and Vogelius, and Li and Nirenberg obtained piecewise $C^{1,γ}$-regularity for linear elliptic problems with piecewise $C^γ$-coefficients which come from composite materials. In this paper, we obtain piecewise $C^{m+1,γ}$-regularity for linear elliptic systems with piecewise $C^{m,γ}$-coefficients which also come from composite materials. This answers the open problem suggested by Li and Vogelius, and Li and Nirenberg.
