In this paper, we consider the Zakharov-Kuznetsov equation in 3D, with a dissipative term of order $ 0 < \alpha \leq 2 $ in the $ x $ direction. We prove that the problem is locally well-posed in $ H^{s}( { I\!\!R}^3) $, for $ s > 1-\frac{\alpha}{2} $, and by an a priori energy estimate, we prove that the problem is globally well-posed in $ H^{1}( { I\!\!R}^3) $.

3D耗散Zakharov-Kuznetsov方程在能量空间中的局部和全局适定性

在本文中,我们考虑3D的Zakharov-Kuznetsov方程,其耗散项在$ x $方向上为$ 0 <\ alpha \ leq 2 $。我们证明问题在$ H ^ {s}({I \!\!R} ^ 3)$中局部存在,当$ s> 1- \ frac {\ alpha} {2} $时,作为先验能量估计,我们证明问题在$ H ^ {1}({I \!\!R} ^ 3)$中是恰当的。
