Chengchun Hao

摘要:

本文研究了具有非零$λ\in \Real$和任意实数$k\gs 5$的$iu_t-u_{xx}+iλ\abs{u}^k u_x=0$形式的一维导数非线性薛定谔方程.利用规范变换和Littlewood-Paley分解,在$H^{1/2}$中建立了具有任意初始值的Cauchy问题的局部适定性.

英文摘要:

In this paper, we investigate the one-dimensional derivative nonlinear Schrödinger equations of the form $iu_t-u_{xx}+iλ\abs{u}^k u_x=0$ with non-zero $λ\in \Real$ and any real number $k\gs 5$. We establish the local well-posedness of the Cauchy problem with any initial data in $H^{1/2}$ by using the gauge transformation and the Littlewood-Paley decomposition.
