摘要
The initial value problem for two-dimensional Zakharov-Kuznetsov equation is shown to be globally well-posed in H^s(R^2)for all 5/7<s<1 via using I-method in the context of atomic spaces.By means of the increment of modified energy,the existence of global attractor for the weakly damped,forced Zakharov-Kuznetsov equation is also established in H^s(R^2)for10/11<s<1.
