关于包含${\cal A}_{p(\cdot)}$ -Laplace算子的PDE

On a PDE involving the ${\cal A}_{p(\cdot)}$-Laplace operator

Mihai Mihăilescu, Dušan Repovš

摘要:

本文建立了一类具有变指数增长条件的微分算子的偏微分方程解的存在性。该算子表示$p(\cdot)$ -拉普拉斯算子的推广,即$Δ_{p(\cdot)}u={\rm div}(|\nabla u|^{p(\cdot)-2}\nabla u)$,其中$p(\cdot)$是连续函数。主要结果的证明是基于Schauder的不动点定理结合适当的变分论点。这里使用的函数空间设置对变指数勒贝格空间和索伯列夫空间有吸引力。

英文摘要:

This paper establishes existence of solutions for a partial differential equation in which a differential operator involving variable exponent growth conditions is present. This operator represents a generalization of the $p(\cdot)$-Laplace operator, i.e. $Δ_{p(\cdot)}u={\rm div}(|\nabla u|^{p(\cdot)-2}\nabla u)$, where $p(\cdot)$ is a continuous function. The proof of the main result is based on Schauder's fixed point theorem combined with adequate variational arguments. The function space setting used here makes appeal to the variable exponent Lebesgue and Sobolev spaces.
