Dear Firedrakers, we have recently finished an online reading group going through Doug Arnold's finite element exterior calculus book. We're now planning the next thing to attack. My proposal, since it intersects with the interests of a number of people who have already been involved, is to read through Joachim Schoeberl's thesis on parameter robust multigrid methods (https://www.asc.tuwien.ac.at/~schoeberl/wiki/publications/diss.pdf). It provides an overview of additive Schwarz theory and multigrid methods, and analysis of convergence and robustness, and is generally a nice thesis on finite element methods and their analysis. Our present schedule has been at 14:00 BST (13:00 UTC) on Mondays, via Zoom. This works well for Europeans, but if enough west-pondians want to join we may consider moving (within the constraints of fitting the working day). The format is informal, and you don't have to have done any prep unless you're presenting (or want to). If you're interested, please let me know (and whether the proposed time is suitable). I'll then try and cook up a schedule and send out zoom links. Cheers, Lawrence
