Nonexistence of minimal mass blow-up solution for the 2D cubic Zakharov-Kuznetsov equation

Gong Chen, Yang Lan, Xu Yuan

For the 2D cubic (mass-critical) Zakharov-Kuznetsov equation, \begin{equation*} \partial_tϕ+\partial_{x_1}(Δϕ+ϕ^3)=0,\quad (t,x)\in [0,\infty)\times \mathbb{R}^{2}, \end{equation*}…
