Sign-Changing Solutions to the Schrödinger Equations Coupled with a Neutral Scalar Field

Year: 2025

Type: article

Abstract: Here we consider the problem of the Schrödinger equation coupled with a neutral scalar field. Through the methods of descending flow invariant sets via the Ljusternik–Schnirelman theory, we rigorously demonstrate the existence of infinitely many sign-changing solutions.
