A stationary approach to the existence and completeness of long-range wave operators

  • Teruo Ikebe
  • Hiroshi Isozaki


The modified wave operators intertwining the Schrödinger operators − Δ and − Δ + V(x), where V(x) is a real long-range potential, are shown to exist and to be complete. The method employed is entirely stationary (time-independent) : One constructs complete stationary wave operators, utilizing a spectral representation (eigenfunction expansion) theory, and then shows that the time-dependent modified wave operators exist and are equal to the stationary ones already constructed.
