摘要
In this paper, we study the following quasilinear Schrodinger equation of the form -Delta u + V(x)u - Delta(u(2))u - g(x,u), x is an element of R-N where the potential V(x) is allowed to be sign-changing, and the primitive of the nonlinearity g(x, u) is of superlinear growth at infinity in u and is also allowed to be sign-changing. We obtain the existence of infinitely many nontrivial solutions by using dual approach and Mountain Pass Theorem. (C) 2014 Elsevier Inc. All rights reserved.
