报告摘要:For a fixed bounded Lipschitz domain and a family of systems of linear elasticity with rapidly oscillating periodic coefficients, we investigate a necessary and sufficient condition that an $A_1$ weight $\omega$ must satisfy in order for the weighted $W^{1,2}(\omega)$ estimates for weak solutions of Neumann problems to be true. Moreover, in any Lipschitz domain, we prove that the uniform $W^{1,p}$ estimates for solutions to the Neumann problem hold for $\frac{2d}{d+1}-\delta
