We consider the defocusing nonlinear Schrödinger equation, with time-dependent potential, in
space dimensions
and
, with
nonlinearity
,
an odd integer,
satisfying

.
We also allow a metric perturbation, assumed to be compactly supported in spacetime,
and nontrapping. We work with module regularity spaces, which are defined by regularity
of order
under the action of certain vector fields generating symmetries of the free
Schrödinger equation. We solve the large data final state problem, with final state in
a module regularity space, and show convergence of the solution to the final
state.
