| Abstract: | In this paper the author applies the implicit midpoint scheme (IM) toher Hamiltonian system for large time, with the fixed time step (△t) to be 0.1. Two velicities whose initial data differ by a gradientyield the same velocity field for all time: the author has verified thisin a numerical experiment using the IM scheme, up to t=2. |
