*讲座内容简介：

We talk about quantitative estimates in periodic homogenization of second-order elliptic systems of elasticity with singular fourth-order perturbations. The convergence rates, which depend on the scale $\kappa$ that represents the strength of the singular perturbation and on the length scale $\varepsilon$ of the heterogeneities, will be presented. We also give the large-scale Lipschitz estimate, down to the scale $\varepsilon$ and independent of $\kappa$. The talk is based on a joint work with Pro. Zhongwei Shen.
