Existence and uniqueness results for Kirchhoff–Schrödinger–Poisson system with general singularity

In this paper, under the general singular assumptions on f, we discuss the existence and uniqueness of solution to a class of Kirchhoff-Schrodinger-Poisson system. For the existence of solution, we assume that f is nonincreasing on (0, delta] and satisfies general singularity at zero, and sublinear growth at infinity. Furthermore, we also obtain the unique result assuming that f satisfies one side Lipschitz condition on [delta, infinity). The variational method is employed to discuss the existence and uniqueness of solution to this system.
