We study the homogenization of a fourth-order divergent elliptic operator $A_\varepsilon$ with rapidly oscillating $\varepsilon$-periodic coefficients, where $\varepsilon$ is a small parameter. The homogenized operator $A_0$ is of the same type and has constant coefficients. We apply Zhikov’s shift method to obtain an estimate in the $(L^2\to L^2)$-operator norm of order $\varepsilon^2$ for the difference of the resolvents $(A_\varepsilon+1)^{-1}$ and $(A_0+1)^{-1}$.

四阶椭圆算子均质化中的近似解算子

我们研究了$ A_ \ varepsilon $具有快速振荡$\varepsilon$周期系数的四阶发散椭圆算子的同质化,其中$\varepsilon$是一个小参数。同质化算子$ A_0 $是同类型的,并且具有常数系数。我们应用Zhikov的转移方法以获得一个估计$(L ^ 2 \至L ^ 2)$的顺序-运算符规范$ \ varepsilon ^ 2 $的解式的差异$(A_ \ varepsilon + 1)^ { -  1} $$(A_0 + 1)^ { -  1} $
