Ground state solutions for the asymptotically periodic Schrödinger-Poisson systems with $p$-Laplacian

In this paper we study the existence of ground state solutions for the asymptotically periodic Schrödinger-Poisson systems which are coupled by a Schrödinger equation of $p$-Laplacian and a Poisson equation of $q$-Laplacian. The method relies on a variational approach and the case of the nonlinearity exhibits a critical growth is also considered. Some results in the literature are extended.
