Numerical Implementation of the Multisymplectic Preissman Scheme and Its Equivalent Schemes
Yushun Wang, Bin Wang, Mengzhao Qin
We analyze the multisymplectic Preissman scheme for the KdV equation with the periodic boundary condition and show that the unconvergence of the widely-used iterative methods to so…
