Multiple solutions and profile description for a nonlinear Schr\"odinger-Bopp-Podolsky-Proca system on a manifold

TL;DR

This paper establishes multiple solutions for a nonlinear Schrödinger-Bopp-Podolsky-Proca system on a compact 3D manifold, using topological methods, and describes the solutions' profiles at low energy levels.

Contribution

It introduces a multiplicity result for the system on manifolds and provides a detailed profile analysis for low energy solutions, extending previous work to a geometric setting.

Findings

Multiple solutions exist for small epsilon on the manifold.

Profile descriptions of low energy solutions are provided.

The proof utilizes Lusternik-Schnirellman category theory.

Abstract

We prove a multiplicity result for \begin{equation*} \begin{cases} -\varepsilon^{2}\Delta_g u+\omega u+q^{2}\phi u=|u|^{p-2}u\\[1mm] -\Delta_g \phi +a^{2}\Delta_g^{2} \phi + m^2 \phi =4\pi u^{2} \end{cases} \text{ in }M, \end{equation*} where $(M,g)$ is a smooth and compact $3$-dimensional Riemannian manifold without boundary, $p\in(4,6)$, $a,m,q\neq 0$, $\varepsilon>0$ small enough. The proof of this result relies on Lusternik-Schnirellman category. We also provide a profile description for low energy solutions.
