Abstract:

In this article, we study the global well-posedness and scattering for the cubic fourth-order Schrödinger equation which is $\dot {H}^{1}$-critical, \begin{align*} \begin {cases} i\partial _tu+\Delta ^2u=-|u|^2u,&(t,x)\in \mathbb {R}\times \mathbb {R}^6,\\ u(0,x)=u_0(x). \end{cases} \end{align*} Inspired by Dodson [Camb. J. Math. 7 (2019), pp. 283–318] and Miao, Xu, and Yang [Commun. Contemp. 22 (2020), p. 1950004], we established the long-time Strichartz estimates in $U_{\Delta ^2}^2$ spaces by using the local smoothing estimate and radial Sobolev embedding. Together with the standard I-method, we proved the improved estimate of modified energy increment to derive the global well-posedness and scattering for radial data in $\dot {H}^{s}$ with $s > \frac {8}{7}$, which extends the previous results of Miao, Wu, and Zhang [Math. Nachr. 288 (2015), pp. 798–823].
