Multiplicity and concentration of solutions for a fractional Schrödinger–Poisson system with sign-changing potential

This paper is concerned with the following fractional Schrodinger–Poisson system: {(−Δ)αu+Vλ(x)u+μϕu=f(x,u)+β(x)|u|ν−2uinR3,(−Δ)tϕ=u2inR3, where μ>0 is a parameter, α,t∈(0,1), ν∈(1,2), 2α+2t>3, Vλ ...
