一类高阶Benjamin-Ono方程的整体适定性和极限行为

Global well-posedness and limit behavior for a higher-order Benjamin-Ono equation

Luc Molinet, Didier Pilod

摘要:

本文证明了高阶Benjamin-Ono方程$$ \partial_tv-b\mathcal{H}\partial^2_xv- aε\partial_x^3v=cv\partial_xv-dε\partial_x(v\mathcal{H}\partial_xv+\mathcal{H}(v\partial_xv)), $$的Cauchy问题在能量空间$H^1(\mathbb R)$中是整体适定的.此外,我们还研究了小正参数$ε$趋于零时的极限行为,并证明了在系数$a$,$b$,$c$和$d$的条件下,该方程的解$v_ε$收敛于Benjamin-Ono方程的相应解.

英文摘要:

In this paper, we prove that the Cauchy problem associated to the following higher-order Benjamin-Ono equation $$ \partial_tv-b\mathcal{H}\partial^2_xv- aε\partial_x^3v=cv\partial_xv-dε\partial_x(v\mathcal{H}\partial_xv+\mathcal{H}(v\partial_xv)), $$ is globally well-posed in the energy space $H^1(\mathbb R)$. Moreover, we study the limit behavior when the small positive parameter $ε$ tends to zero and show that, under a condition on the coefficients $a$, $b$, $c$ and $d$, the solution $v_ε$ to this equation converges to the corresponding solution of the Benjamin-Ono equation.
