Combined Effects of Homogenization and Singular Perturbations
钮维生 教授(安徽大学)
2021年4月2日13:30-14:30  腾讯会议 ID:191 765 193

*主持人:叶东 教授

*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.
