On the Cauchy problem for the inhomogeneous nonlinear Schr\"odinger
equation with inverse-power potential
In this paper, we study the Cauchy problem for the inhomogeneous nonlinear Schr\"{o}dinger equation with inverse-power potential \[iu_{t} +\Delta u-c|x|^{-a}u=\pm |x|^{-b} |u|^{\sigma } u,\;\;(t,x)\in \mathbb R\times\mathbb R^{d},\] where $d\in \mathbb N$, $c\in \mathbb R$, $a,b>0$ and $\sigma>0$. First, we establish the local well-posedness in the fractional Sobolev spaces $H^s(\mathbb R^d)$ …
