Abstract

In this paper we continue to study small amplitude solutions of the damped\ncubic NLS equation, driven by a random force (the study was initiated in our\nprevious work [A.Dymov, S.Kuksin, Comm. Math. Phys.'2021] and continued in\n[A.Dymov, S.Kuksin, A.Maiocchi, S.Vladuts, arXiv:2104.11967]). We write\nsolutions of the equation as formal series in the amplitude and discuss the\nbehaviour of this series under the wave turbulence limit, when the amplitude\ngoes to zero, while the space-period goes to infinity.\n
