Pollution-free and fast hybridizable discontinuous Galerkin solvers for the high-frequency Helmholtz equation
In this work we propose a hybridizable discontinuous Galerkin (hdG) discretization of the high-frequency Helmholtz equation in the presence of point sources and highly heterogeneous and discontinuous wave speed models. We show that it delivers solutions that are provably second-order accurate and do...
