摘要
We describe the construction of almost-periodic solutions for a particular Schrodinger equation on a finite x-interval, depending on some potential V. The construction proceeds by iterating a KAM theorem about the existence of quasiperiodic solutions for some partial differential equations. As a result, we find for,almost all' potentials V uncountably many almost-periodic solutions accumulating at the zero solution.
