A posteriori error estimates for discontinuous Galerkin methods for the generalized Korteweg-de Vries equation
A posteriori error estimates for discontinuous Galerkin methods for the generalized Korteweg-de Vries equation
We construct, analyze and numerically validate a posteriori error estimates for conservative discontinuous Galerkin (DG) schemes for the Generalized Korteweg-de Vries (GKdV) equation. We develop the concept of dispersive reconstruction, i.e., a piecewise polynomial function which satisfies the GKdV equation in the strong sense but with a computable forcing term …
