In this paper we consider the global well-posedness (GWP) and finite time blowup problem for the 3D focusing energy-critical inhomogeneous NLS with spatial inhomogeneity the coefficient such that for . The difficulty of this problem comes from the singularity of . In the previous result (Cho and Lee, 2020; Cho et al., 2020) the authors showed the GWP for by Kenig–Merle argument based on the standard Strichartz estimates. Here we extend the GWP to the coefficient with more serious singularity, . For this purpose, we improve the local theory and develop a new profile decomposition based on weighted Strichartz estimates.

关于聚焦能量关键的非均匀NLS:加权空间方法
在本文中,我们考虑具有空间不均匀性的3D聚焦能量临界不均匀NLS的全局适定性(GWP)和有限时间爆炸问题 这样 对于 。这个问题的困难来自于奇异性。在之前的结果中(Cho和Lee,2020; Cho等,2020),作者展示了由Kenig-Merle根据标准的Strichartz估计得出。在这里,我们将GWP扩展为具有更严重的奇点的系数,。为此,我们改进了局部理论,并基于加权的Strichartz估计开发了新的轮廓分解。
