An algebraic multiscale method for spatial network models
Moritz Hauck, Roland Maier, Axel Målqvist
In this work, we present a multiscale approach for the reliable coarse-scale approximation of spatial network models represented by a linear system of equations with respect to the…

Localized orthogonal decomposition for a multiscale parabolic stochastic partial differential equation
Annika Lang, Per Ljung, Axel Målqvist
A multiscale method is proposed for a parabolic stochastic partial differential equation with additive noise and highly oscillatory diffusion. The framework is based on the localiz…
