 Homogenization of Elliptic Systems with Stratified Structure

  2022.05.11(星期三)上午9:00-10:00

 点:腾讯会议:948-3602-5762

  要:This talk mainly concerns the homogenization of second-order elliptic systems with stratified structure on bounded Lipschitz domains. A brief review on the classical homogenization theory in PDE will be presented first. Under rather general smoothness assumptions on the coefficients, the sharp-order scale-invariant convergence rate in $L^{2d/(d-1)}(\Omega)$ for stratified systems is established. We also study the interior uniform regularity estimates for the system, including the large-scale Lipschitz estimates, $W^{1, p}$ estimates and large-scale Holder estimates.
