Construction of KdV flow
A KdV flow is constructed on a space whose structure is described in terms of the spectrum of the underlying Schr\"odinger operators. The space includes the conventional decaying functions and ergodic ones. Especially any smooth almost periodic function can be initial data for the KdV equation.

the spectrum of the underlying Schr\"odinger operators. The space includes the
conventional decaying functions and ergodic ones. Especially any smooth almost
periodic function can be initial data for the KdV equation. |
