Deep neural networks for geometric multigrid methods

Nils Margenberg, Robert Jendersie, Thomas Richter +1

We investigate scaling and efficiency of the deep neural network multigrid method (DNN-MG). DNN-MG is a novel neural network-based technique for the simulation of the Navier-Stokes…

A Local Spectral Exterior Calculus for the Sphere and Application to the Shallow Water Equations

Clauson Carvalho da Silva, Christian Lessig, Boyko Dodov +2

We introduce $Ψ ec$ , a local spectral exterior calculus for the two-sphere $S^{2}$ . $Ψ ec$ provides a discretization of Cartan's exterior calculus on $S^{2}$ formed by…
