Optimal number of solutions for nonlinear coupled Schrödinger systems. I: Synchronized case
This paper is concerned with the study of a class of semilinear Schrödinger systems with Neumann boundary condition. The main result of this paper establishes a sufficient condition for the existence of positive solutions in the cooperative case. A key tool in the arguments is played by the Lyapunov-Schmidt reduction method.
