Existence of positive bound state solution for the nonlinear Schr?dinger–Bopp–Podolsky system

摘要

In this paper, we study a class of Schr?dinger–Bopp–Podolsky system. Undersome suitable assumptions for the potentials, by developing some calculations of sharpenergy estimates and using a topological argument involving the barycenter function,we establish the existence of positive bound state solution.
