Local well-posedness and finite time blowup for fourth-order Schrödinger equation with complex coefficient

Abstract

We consider the fourth-order Schrödinger equation $$i{\partial }_{t}u+{\Delta }^{2}u+\mu \Delta u+\lambda |u{|}^{\alpha }u=0,$$ where $\alpha >0,\mu =\pm 1$ or $0$ and $\lambda \in \mathbb{C}$. Firstly, we prove local well-posedness in $H^4\left({\mathbb{R}}^N\right)$ in both $H^4$ subcritical and critical case: $\alpha >0$, $(N-8)\alpha \le 8$. Then, for any given compact set $K\subset {\mathbb{R}}^N$, we construct $H^4({\mathbb{R}}^N)$ solutions that are defined on $(-T,0)$ for some $T>0$, and blow up exactly on $K$ at $t=0$.
