Blowup dynamics for Mass Critical Half-wave equation in 3D

Abstract

We consider the half-wave equation $i{u}_t=Du-|u{|}^{\frac{2}{3}}u$ in three dimension and in the mass critical. For initial data $u(t_0,x)=u_0(x)\in H_{rad}^{1/2}({\mathbb{R}}^3)$ with radial symmetry, we construct a new class of minimal mass blowup solutions with the blow up rate $\Vert D^{\frac{1}{2}}u(t){\Vert }_2\sim \frac{C(u_0)}{|t{|}^{\frac{1}{4}}}$ as $t\to 0^{-}$.
