Nondispersive solutions to the mass critical half-wave equation in two dimensions

Abstract

We consider the half-wave equation with mass critical in two dimension \begin{eqnarray*} \begin{cases} iu_t=Du-|u|u,\,\,\, \\ u(0,x)=u_0(x), \end{cases} \end{eqnarray*} First, we prove the existence of a family of traveling solitary waves. We then show the existence of finite-time blowup solutions with minimal mass $\Vert u_0{\Vert }_2=\Vert Q{\Vert }_2$, where $Q$ is the ground state solution of equation $DQ+Q=Q^2$.
