Before revision: A generalized algebraic framework is presented for a broad class of high-order methods for hyperbolic systems of conservation laws on curvilinear unstructured grids. The framework enables the unified analysis of many popular discontinuous Galerkin (DG) and flux reconstruction (FR) schemes based on properties of the matrix operators constituting such discretizations.
After revision: We propose a unifying framework for the matrix-based formulation and analysis of discontinuous Galerkin (DG) and flux reconstruction (FR) schemes based on properties of the matrix operators constituting such discretizations.
