Scattering-like phenomena of the periodic defocusing NLS equation
T. Kappeler, B. Schaad, P. Topalov
In this paper we prove approximation properties of the solutions of the defoucsing NLS equation on the circle by nearly linear flows. In addition we show that spatially periodic so…

Semi-linearity of the non-linear Fourier transform of the defocusing NLS equation
T. Kappeler, B. Schaad, P. Topalov
In this paper we prove that the non-linear Fourier transform of the defocusing NLS equation on the circle is linear up to terms which are one order smoother.
