摘要

We study the scattering and blowup problem for a class of nonlinear Schr?dinger equations with general nonlinearities in the spirit of Kenig and Merle [17]. Our conditions on the nonlinearities allow us to treat a wider class of those than ever treated by several authors, so that we can prove the existence of a ground state (a standing-wave solution of minimal action) for any frequency ω > 0. Once we get a ground state, a so-called potential-well scenario works well: for the nonlinear dynamics determined by the nonlinear Schr?dinger equations, we define two invariant regions A_(ω,+) and A_(ω,-) for each ω > 0 in H~1(R~d) such that any solution starting from A_(ω,+) behaves asymptotically free as t → ±1, one from A_(ω,-) blows up or grows up, and the ground state belongs to A_(ω,+)∩A_(ω,-). Our weaker assumptions as to the nonlinearities demand that we argue in a subtle way in proving the crucial properties of the solutions in the invariant regions.
