Einladung zum Mathematischen Kolloquium
Mittwoch, den 26. Juni 2024, Konferenzraum (R107), 17 Uhr s.t.
Professor Dr. Ralf Kornhuber , AG Numerische Analysis Partieller Differentialgleichungen, FU Berlin spricht über das Thema: " Numerical Homogenization and Subspace Correction“
Abstract: Solutions of multiscale problems typically combine reasonable large-scale properties with irregular behavior on fine scales, the resolution of which finally dominates the overall computational cost.
We first consider elliptic equations with (non-periodically) oscillating coefficients as a model problem and present recent results on iterative homogenization by subspace decomposition and on orthogonal decomposition with localization by local smoothing. As an outlook towards frictional fault networks from the geosciences, we then apply these techniques to fractal interface problems.
