On a technique for reducing spurious oscillations in DG solutions of convection-diffusion equations

This note studies a generalization of a post-processing technique and a novel method inspired by the same technique which significantly reduce spurious oscillations in discontinuous Galerkin solutions of convection-diffusion equations in the convection-dominated regime.

Keywords
