A high-order approach to elliptic multiscale problems
A talk in the BI.discrete series by
Roland Maier from Friedrich-Schiller-Universität (Jena)
| Abstract: |
In this talk, we present a multiscale approach for an elliptic setting with
general unstructured and highly varying diffusion coefficients. The approach
enables high-order convergence rates with respect to the mesh parameter and
the polynomial degree. The method allows for suitable localization and does
not rely on additional regularity assumptions on the domain, the diffusion
coefficient, or the exact (weak) solution as typically required for
high-order approaches. We discuss rigorous a priori error estimates with
respect to the involved discretization parameters, and the interplay between
these parameters. Further, we present numerical examples that illustrate the
practical performance of the method.
