Abstract
- In this paper we consider the long time behavior of solutions to the cubic nonlinear Schrödinger equation (NLS) posed on the spatial domain ℝ X 핋d, 1 ≤ d ≤ 4. We first prove the local well-posedness in C(I; L²xHsy} ⋂ C (I ; LXx,y) for solutions with initial data U0 ∈ Hx0,1 L²y ⋂ L²x Hsy. Then, for sufficiently small, smooth, decaying data, we prove global existence and derive modified asymptotic dynamics by using the wave packet method and normal form corrections. The modified scattering behavior on ℝ X 핋d combines the modified scattering of the cubic NLS on real line R with cubic NLS dynamics on the torus. We also consider the corresponding asymptotic completeness problem. [ABSTRACT FROM AUTHOR]
