摘要：
In this paper, we deal with multiplicity of solutions of a class of sublinear Schrodinger-Maxwell equations {-Delta u + V(x)u + phi u = f (x, u), in R-3, -Delta phi = u(2); lim(vertical bar x vertical bar ->infinity) phi(x) = 0, in R-3. Under more relaxed assumptions on V and f, we establish some existence criteria to guarantee that the above problem has at least one or infinitely many nontrivial solutions by using the genus properties in critical theory.
