Abstract

We consider the Schr\"odinger equation with a general interaction term, which is localized in space, for radially symmetric initial data in nn dimensions, n5n\geq5. The interaction term may be space-time dependent and nonlinear. Assuming that the solution is bounded in H1(Rn)H^1(\mathbb{R}^n) uniformly in time, we prove soliton resolution conjecture (Asymptotic completeness) by demonstrating that the solution resolves into a smooth and localized part and a free radiation in Lx2(Rn)\mathcal{L}^2_x(\mathbb{R}^n) norm. Examples of such equations include inter-critical and super-critical nonlinear Schr\"odinger equations, saturated nonlinearities, time-dependent potentials, and combinations of these terms.
