Instability of the solitary waves for the generalized Boussinesq equations
Li, Bing; Ohta, Masahito; Wu, Yifei; Xue, Jun (Peer reviewed; Journal article, 2020)In this work, we consider the following generalized Boussinesq equation \begin{align*} \partial_{t}^2u-\partial_{x}^2u+\partial_{x}^2(\partial_{x}^2u+|u|^{p}u)=0,\qquad (t,x)\in\R\times \R, \end{align*} with $0<p<\infty$. ... -
Optimal small data scattering for the generalized derivative nonlinear Schrödinger equations
Bai, Ruobing; Wu, Yifei; Xue, Jun (Peer reviewed; Journal article, 2020)In this work, we consider the following generalized derivative nonlinear Schr\"odinger equation \begin{align*} i\partial_t u+\partial_{xx} u +i |u|^{2\sigma}\partial_x u=0, \quad (t,x)\in \R\times \R. \end{align*} We prove ...
