In this paper, we consider the following Schrödinger–Poisson system with singularity
where
Ω⊂R3 is a smooth bounded domain with boundary ∂Ω,
41125bc28f1a8d863bb0ba8f" title="Click to view the MathML source">η=±1,
r∈(0,1) is a constant,
μ>0 is a parameter. We obtain the existence and uniqueness of positive solution for
η=1 and any
μ>0 by using the variational method. The existence and multiplicity of solutions for the system are also considered for
η=−1 and
μ>0 small enough by using the method of Nehari manifold.
