We consider the Cauchy problem for the inhomogeneous nonlinear Schrödinger (INLS) equa-where n ∈ N, 0 < s < min{n, 1 + n/2}, 0 < b < min{2, n − s, 1 + n−2s 2 } and f (u) is a nonlinear function that behaves like λ |u| σ u with σ > 0 and λ ∈ C. Recently, An-Kim [1] proved the local existence of solutions in H s (R n ) with 0 ≤ s < min{n, 1+n/2}. However even though the solution is constructed by a fixed point technique, continuous dependence in the standard sense in H s (R n ) with 0 < s < min{n, 1 + n/2} doesn't follow from the contraction mapping argument. In this paper, we show that the solution depends continuously on the initial data in the standard sense in H s (R n ), i.e. in the sense that the local solution flow is continuous H s (R n ) → H s (R n ), if σ satisfies certain assumptions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
