摘要:

在本文中,我们开发和使用连续平均方法来解释正则化机制的周期Korteweg-de Vries(KdV)方程在齐次索伯列夫空间$\dot{H}^s$,$s\ge0$。具体来说,我们证明了整体存在性,唯一性,Lipschitz连续依赖于初始数据的周期KdV的解决方案。对于初始数据是在$L_2$的情况下,我们还显示了Lipschitz连续依赖这些解决方案相对于初始数据的映射从$\dot{H}^s$到$\dot{H}^s$,为$s\in(-1,0]$。

英文摘要:

In this paper we develop and use successive averaging methods for explaining the regularization mechanism in the the periodic Korteweg--de Vries (KdV) equation in the homogeneous Sobolev spaces $\dot{H}^s$, for $s\ge0$. Specifically, we prove the global existence, uniqueness, and Lipschitz continuous dependence on the initial data of the solutions of the periodic KdV. For the case where the initial data is in $L_2$ we also show the Lipschitz continuous dependence of these solutions with respect to the initial data as maps from $\dot{H}^s$ to $\dot{H}^s$, for $s\in(-1,0]$.
