摘要: In this article, we are concerned with the existence of solutions of a quasilinear elliptic equation in RN which includes the so-called modified nonlinear Schrödinger equation as a special case. Combining the dual approach and the nonsmooth critical point theory, we obtain the existence of a nontrivial solution.
