在本文中,我们研究了以下广义拟线性薛定谔方程− d i v (g 2 (u)∇ u)+ g (u) g′(u)|∇ u| 2+ V (x) u= f (x, u), x∈ R N,其中 N≥ 3, 2*= 2 N N− 2, g∈ C 1 (R, R+),V (x) 和 f (x, u) 在 x 上是 1-周期。通过使用变量的变化,我们获得基态解的存在性。与 Nahari 流形方法不同,我们方法的主要思想在于使用对角线方法找到流形外能量泛函的最小化 Cerami 序列。
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.
