Changxing Miao, Haigen Wu, Junyong Zhang

摘要:

在低正则性空间$H^s(\R^n)$中研究了具有$s<2$的三次四阶薛定谔方程$iu_t+Δ^2u+|u|^2u=0$的整体解的存在性和散射性.我们提供了另一种方法来获得一个新的相互作用Morawetz估计和扩展的范围的互动估计Pausader \cite{P08}通过修改的张量积方法出现在\cite{CGT}。我们结合相互作用Morawetz估计,能量增量的I-方法来证明的结果。

英文摘要:

We investigate the global existence and scattering for the cubic fourth-order Schrödinger equation $iu_t+Δ^2u+|u|^2u=0$ in the low regularity space $H^s(\R^n)$ with $s<2$. We provide an alternative approach to obtain a new interaction Morawetz estimate and extend the range of the dimension of the interactive estimate in Pausader \cite{P08} by modifying a tensor product method appeared in \cite{CGT}. We combine interaction Morawetz estimates, energy increments for the I-method to prove the result.
