In this paper, we study the following generalized quasilinear Schrödinger equation− d i v (g 2 (u)∇ u)+ g (u) g′(u)|∇ u| 2+ V (x) u= f (x, u), x∈ R N, where N≥ 3, 2∗= 2 N N− 2, g∈ C 1 (R, R+), V (x) and f (x, u) are 1-periodic on x. By using a change of variable, we obtain the existence of ground states solutions. Unlike the Nahari manifold method, the main idea of our approach lies on finding a minimizing Cerami sequence for the energy functional outside the manifold by using the diagonal method.
