| Abstract: | The following two level semi-explicit difference schemes are constructed for solv- ing the dispersive equation u_t=au_(xxx), P2R. R2L. C2R. C2L. The local truncation errors for the schemes P and C are 0( ) and 0( ) respectively. These chassos of the diffcrence schemes arc absolutely stable and can be caiculated explicitly. |
