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…

A generalized finite element method for the strongly damped wave equation with rapidly varying data
Per Ljung, Axel Målqvist, Anna Persson
We propose a generalized finite element method for the strongly damped wave equation with highly varying coefficients. The proposed method is based on the localized orthogonal deco…
