An adaptive localized orthogonal decomposition method for Helmholtz problems

We develop an adaptive localized orthogonal decomposition (ALOD) method for Helmholtz problems with localized oscillations and singularities. The main result is the first wavenumber-robust residual a posteriori error estimate for a Helmholtz LOD discretization within the standard resolution, oversampling, and discrete-...
