Hu–Atkins conjecture on superconvergent dispersion-dissipation errors for DG methods
Let denote the polynomial degree of a discontinuous Galerkin (DG) spatial discretization, and consider its dispersion-dissipation relations for a linear hyperbolic problem. Hu–…

The locally symmetric patch explanation for superconvergence of Raviart–Thomas recovery
For the triangular grids and recovery operators under consideration, locally symmetric patches are patches whose surrounding mesh configuration has the symmetry needed to support c…
