Homogenization for Partial Differential Equations (SS2025)

Zeit/Ort: tba

Semesterwochenstunden: 4

Vorlesungssprache: Englisch


In this lecture we deal with mathematical methods of multi-scale analysis for the treatment of problems in heterogeneous media. Starting from a microscopic model which describes the heterogeneous structure (and the physical processes) using oscillatory coefficients or geometry, the goal is to derive macroscopic models with homogenized/effective coefficients that provide an approximation of the microscopic model. For this purpose, we use rigorous techniques such as two-scale convergence, where we restrict ourselves to periodic problems. As applications, we will consider the diffusion equation and Darcy's law. The latter can be derived from the Stokes equation in (periodically) perforated domains by means of homogenization.
