| Outline of Final Research Achievements |
First, we proved the global well-posedness and asymptotic behavior of the Cauchy problem of Zakharov system in higher dimensions. We used the theory of Up, Vp space to prove it. The main difficulty comes from the difference of the properties of the linear equations. To overcome it, we used the intersection space of V2 space and Lebesgue space related to the end-point Strichartz estimate. Second, we categolized the fifth order KdV type equations. By using the normal form reduction, energy method and Bona-Smith approximation, we proved that the local well-posedness and parabolic smoothing effect.
