Normalized solutions for Schödinger equations with potential and general nonlinearities involving critical case on large convex domains (2311.04914v1)

Published 3 Nov 2023 in math.AP

Abstract: In this paper, we study the following Schr\"odinger equations with potentials and general nonlinearities \begin{equation*} \left{\begin{aligned} & -\Delta u+V(x)u+\lambda u=|u|{q-2}u+\beta f(u), \ & \int |u|2dx=\Theta, \end{aligned} \right. \end{equation*} both on $\mathbb{R}N$ as well as on domains $r \Omega$ where $\Omega \subset \mathbb{R}N$ is an open bounded convex domain and $r>0$ is large. The exponent satisfies $2+\frac{4}{N}\leq q\leq2*=\frac{2 N}{N-2}$ and $f:\mathbb{R}\rightarrow \mathbb{R}$ satisfies $L2$-subcritical or $L2$-critical growth. This paper generalizes the conclusion of Bartsch et al. in \cite{TBAQ2023}(2023, arXiv preprint). Moreover, we consider the Sobolev critical case and $L2$-critical case of the above problem.
