Mounir Hsini

摘要:

本文证明了下列非线性椭圆方程组{lll} -Δ_{p(x)}u = a(x)|u| ^{p(x)-2} u-b(x)|u| ^{α(x)} |v| ^{β(x)} v + f(x)在Ω中的弱解的存在性,Δ_{q(x)}v = c(x)|v| ^{q(x)-2} v-d(x)|v| ^{β(x)} |u| ^{α(x)} u + g(x),单位为Ω,u = v = 0 \quad在\partial Ω上,其中$Ω$是$\mathbb{R}^N$的一个开有界区域,$\partialΩ$是$p(x)$-Laplacian算子,$Δ_{p(x)}$是$p(x)$-Laplacian算子,利用单调算子理论证明了该方程弱解的存在性.当$Ω=\mathbb{R}^N$ .

英文摘要:

In this paper, we prove the existence of weak solutions for the following nonlinear elliptic system {lll} -Δ_{p(x)}u = a(x)|u|^{p(x)-2}u - b(x)|u|^{α(x)}|v|^{β(x)} v + f(x) in Ω, Δ_{q(x)}v = c(x) |v|^{q(x)-2}v - d(x)|v|^{β(x)}|u|^{α(x)} u + g(x) in Ω, u = v = 0 \quad on \partialΩ, where $Ω$ is an open bounded domains of $\mathbb{R}^N$ with a smooth boundary $\partialΩ$ and $Δ_{p(x)}$ denotes the $p(x)$-Laplacian.The existence of weak solutions is proved using the theory of monotone operators. Similar result will be proved when $Ω=\mathbb{R}^N$.
