a multigrid method?
Felix Baumann (Zuse-Institut Berlin)
Due to the current situation, the talk takes place online, via zoom. The meeting link has been sent out via the usual mailing lists; please contact the organisers if you have not received the email and would like to join the talk.
The discretization of PDEs leads to linear systems with a very large number of unknowns. While direct solvers fail due to the large scale, Multigrid Methods provide a powerful solution technique. In this talk we present the core ideas behind the Multigrid Method and discuss mesh-independent convergence and its optimal complexity.
