We prove that certain Sobolev-type norms, slightly stronger than those given by energy conservation, stay bounded uniformly in time and N. This allows one to extend the local existence results of the second and third author globally in time. The proof is based on interaction Morawetz-type estimates and Strichartz estimates (including some new end-point results) for the equation \ (1)/(i)∂t-Δx-Δy+(1)/(N)VN(x-y) \Λ(t, x, y) =F in mixed coordinates such as Lp(dt) Lq(dx) L2(dy), Lp(dt) Lq(dy) L2(dx), Lp(dt) Lq(d(x-y)) L2(d(x+y)). The main new technical ingredient is a dispersive estimate in mixed coordinates, which may be of interest in its own right.
