三维Zakharov系统的散射

Scattering for the Zakharov system in 3 dimensions

Zaher Hani, Fabio Pusateri, Jalal Shatah

摘要:

我们证明了3维空间中Zakharov系统Cauchy问题小局部解的整体存在性和分散性。波分量以最佳速率t^{-1}逐点衰减,而薛定谔分量几乎以速率t^{-7/6}衰减。

英文摘要:

We prove global existence and scattering for small localized solutions of the Cauchy problem for the Zakharov system in 3 space dimensions. The wave component is shown to decay pointwise at the optimal rate of t^{-1}, whereas the Schrödinger component decays almost at a rate of t^{-7/6}.
