Global well-posedness for a $L^2$-critical nonlinear higher-order Schrödinger equation
Abstract
We prove the global well-posedness for a $L^2$-critical defocusing cubic higher-order Schrödinger equation, namely \[ i\partial_t u + Λ^k u = -|u|^2 u, \] where $Λ=\sqrt{-Δ}$ and $k\geq 3, k \in \mathbb{Z}$ in $\mathbb{R}^k$ with initial data $u_0 \in H^γ, γ>γ(k):=\frac{k(4k-1)}{14k-3}$.
