Adaptive multigrid for high-order discontinuous Galerkin methods based on the full approximation scheme
An adaptive multigrid method for discontinuous Galerkin formulations of elliptic problems using Brandt's full approximation scheme (FAS), designed for unstructured curvilinear meshes but maintains a tensor-product structure for fast diagonalization.
