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 u02=Q2\|u_0\|_2=\|Q\|_2, where QQ is the ground state solution of equation DQ+Q=Q2DQ+Q=Q^2.
