一类Boussinesq型系统的Cauchy问题

On the Cauchy problem for a Boussinesq type system

Felipe Linares, Mahendra Panthee, Jorge Drumond Silva

摘要:

考虑一类Boussinesq型方程组的初值问题.重写后的系统耦合KdV型方程的等价形式,我们证明了这是局部适定的$(H^s(\R^2))^4$,$s>3/2$,使用尖锐的平滑估计。因此,我们在$H^s\times \mathcal{V}^{s+1}$中得到了原始系统的局部适定性结果,对于$s>3/2$(参见下面的$\mathcal{V}^{s}$的定义)。

英文摘要:

We consider the initial value problem (IVP) associated to a Boussinesq type system. After rewriting the system in an equivalent form of coupled KdV-type equations, we prove that this is locally well-posed in $(H^s(\R^2))^4$, $s>3/2$, using sharp smoothing estimates. Consequently we obtain the local well-posedness result for the original system in $H^s\times \mathcal{V}^{s+1}$ for $s>3/2$ (see below for the definition of $\mathcal{V}^{s}$).
