Infinitely Many Solutions of Schrodinger-Poisson Equations with Critical and Sublinear Terms

In this paper, we study the following Schrodinger-Poisson equations -Delta u+u+phi u=u5+lambda a R3,-Delta phi=u2,x is an element of Double-struck capital R3, where the parameter lambda>0 and p is an element of When the parameter lambda is small and the weight function fills some appropriate conditions, we admit the Schrodinger-Poisson equations possess infinitely many negative energy solutions by using a truncation technology and applying the usual Krasnoselskii genus theory. In addition, a byproduct is that the set of solutions is compact.
