Asymptotic stability of smooth solitons and multi-solitons for the Camassa--Holm equation
Robin Ming Chen, Yang Lan, Yue Liu +1
We establish the asymptotic stability of smooth solitons and multi-solitons for the Camassa-Holm (CH) equation in the energy space . We show that solutions initially close…

Construction of blow-up solution with minimal mass for 2D cubic Zakharov--Kuznetsov equation
Yang Lan, Xu Yuan
In this article, we construct a minimal mass blow-up solution of the two-dimensional cubic (mass-critical) Zakharov--Kuznetsov equation: \begin{equation*} \partial_t ϕ+\partial_{x_…

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*}…
