一个改进的存在性判据和一个最优结果

An improved existence criterion and an optimal result

Zakaria Boucheche

摘要:

研究了$\mathbb{R}^n,\,n\geq 5,$的光滑有界区域$Ω$上的半线性椭圆型方程,该方程包含临界非线性项和线性项,分别为$K(x)u^{(n+2)/(n-2)}$和$μu,$.利用检验函数方法,给出了参数$μ$和函数$K(x).$的一个存在性准则.对于$Ω,\,K(x)$和$n,$的一个特殊情况,我们利用Pohozaev型恒等式证明了它的最优性.

英文摘要:

We are concerned with a semi-linear elliptic equation on a smooth bounded domain $Ω$ of $\mathbb{R}^n,\,n\geq 5,$ which involves a critical nonlinearity and a linear term of the form $K(x)u^{(n+2)/(n-2)}$ and $μu,$ respectively. By using a test function procedure, we give an existence criterion involving the parameter $μ$ and the function $K(x).$ For a particular case of $Ω,\,K(x)$ and $n,$ we prove its optimality through a Pohozaev type identity.
