Infinitely many solutions for Schrödinger-Maxwell equations with indefinite sign subquadratic potentials
In this paper, we deal with multiplicity of solutions of a class of sublinear Schrodinger-Maxwell equations-@Du+V(x)u+@fu=f(x,u),inR^3,-@D@f=u^2,lim|x|->~@f(x)=0,inR^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.
