摘要

对于含有$s>\max\{ 2 + \frac1p , \frac52\} $、$p \in (1,\infty]$和$r \in [1 , \infty)$的Besov空间$B^s_{p,r}(\rr)$，证明了FORQ方程的数据-解映射从$B^s_{p,r}(\rr)$到$C([0,T]; B^s_{p,r}(\rr))$不是一致连续的。非一致相关性的证明是基于近似解和Littlewood-Paley分解。

Continuity of the data-to-solution map for the FORQ equation in Besov spaces

For Besov spaces $B^s_{p,r}(\rr)$ with $s>\max\{ 2 + \frac1p , \frac52\} $, $p \in (1,\infty]$ and $r \in [1 , \infty)$, it is proved that the data-to-solution map for the FORQ equation is not uniformly continuous from $B^s_{p,r}(\rr)$ to $C([0,T]; B^s_{p,r}(\rr))$. The proof of non-uniform dependence is based on approximate solutions and the Littlewood-Paley decomposition.
