无Ambrosetti-Rabinowitz条件下具有亚临界和临界增长的$\mathbb{R}^{N}$中的N-Laplacian方程

N-Laplacian equations in $\mathbb{R}^{N}$ with subcritical and critical growth without the Ambrosetti-Rabinowitz condition

摘要:

设$Ω$是$\mathbb{R}^N$中的有界域.本文考虑如下非线性椭圆型方程:$N$ -Laplacian型方程:$-Δ_{N}u=f(x,u)$其中当$f$是次临界或临界指数增长时,$u\in W_{0}^{1,2}\{0}$.这种非线性是由Moser-Trudinger不等式激发的。事实上,我们将证明在没有Ambrosetti-Rabinowitz $(AR)$条件的情况下,上述方程存在非平凡非负解。当非线性项$f$具有指数增长时,文献中关于$\mathbb{R}^{N}$中$N-$ Laplacian非平凡解的存在性的早期工作只处理当$f$满足$(AR)$条件时的情况。我们的方法是基于一个合适的版本的山路定理介绍G。Cerami \cite{Ce1, Ce2}。这种方法也可以用来产生的$p$ -拉普拉斯方程($1<p<N$)在亚临界多项式增长的情况下的存在性结果。

英文摘要:

Let $Ω$ be a bounded domain in $\mathbb{R}^N$. In this paper, we consider the following nonlinear elliptic equation of $N$-Laplacian type: $-Δ_{N}u=f(x,u)$ where $u\in W_{0}^{1,2}\{0}$ when $f$ is of subcritical or critical exponential growth. This nonlinearity is motivated by the Moser-Trudinger inequality. In fact, we will prove the existence of a nontrivial nonnegative solution to the above equation without the Ambrosetti-Rabinowitz $(AR)$ condition. Earlier works in the literature on the existence of nontrivial solutions to $N-$Laplacian in $\mathbb{R}^{N}$ when the nonlinear term $f$ has the exponential growth only deal with the case when $f$ satisfies the $(AR)$ condition. Our approach is based on a suitable version of the Mountain Pass Theorem introduced by G. Cerami \cite{Ce1, Ce2}. This approach can also be used to yield an existence result for the $p$-Laplacian equation ($1<p<N$) in the subcritical polynomial growth case.
