. We are interested in the influence of filtering the positive Fourier modes to the integrable non linear Schr¨odinger equation. Equivalently, we want to study the effect of dispersion added to the cubic Szeg˝o equation, leading to the NLS-Szeg˝o equation on the circle S 1 There are two sets of results in this paper. The first result concerns the long time Sobolev estimates for small data. The second set of results concerns the orbital stability of plane wave solutions. Some instability results are also obtained, leading to the wave turbulence phenomenon.
