摘要:

In this paper, we study the following generalized quasilinear Schrödinger equations with critical or supercritical growths
-div(g2(u)∇u) + g(u)g'(u)|∇u|2 + V (x)u=f(x, u) + λ|u|p-2u, x ∈ RN,
where λ > 0, N ≥ 3, g:R → R+ is a C1 even function, g(0)=1, g'(s) ≥ 0 for all s ≥ 0,???20170623???((g(s))/(|s|α-1)):=β > 0 for some α ≥ 1 and (α-1)g(s) > g'(s)s for all s > 0 and pα2*. Under some suitable conditions, we prove that the equation has a nontrivial solution for small λ > 0 using a change of variables and variational method.
