Convergence of finite difference methods for the wave equation in two space dimensions
Siyang Wang, Anna Nissen, Gunilla Kreiss
When using a finite difference method to solve an initial--boundary--value problem, the truncation error is often of lower order at a few grid points near boundaries than in the in…
