Abstract

For a given Finsler-Minkowski norm $\mathcal{F}$ in $\mathbb{R}^N$ and a bounded smooth domain $\Omega\subset\mathbb{R}^N$ $\big(N\geq 2\big)$, we establish the following weighted anisotropic Sobolev inequality $$ S\left(\int_{\Omega}|u|^q f\,dx\right)^\frac{1}{q}\leq\left(\int_{\Omega}\mathcal{F}(\nabla u)^p w\,dx\right)^\frac{1}{p},\quad\forall\,u\in W_0^{1,p}(\Omega,w)\leqno{\mathcal{(P)}} $$ where $W_0^{1,p}(\Omega,w)$ is the weighted Sobolev space under a class of $p$-admissible weights $w$, where $f$ is some nonnegative integrable function in $\Omega$. We discuss the case $0

具有极值和相关奇异问题的加权各向异性Sobolev不等式
对于$\mathbb{R}^N$中给定的Finsler-Minkowski范数$\mathcal{F}$和有界光滑域$\Omega\subet\mathbb{R}^N$\big(N\geq2\big)$,我们建立了以下加权各向异性Sobolev不等式$S\left(\int_{\Omega}|u|^qf\,dx\right)^\frac{1}{p},\fquad\fall\,u\在W_0^{1,p}(\Omega,W)\leqno{\mathcal{(p)}$$中,其中$W_0^{1,p}(\Omeca,W)$是一类$p$可容许权$W$下的加权Sobolev空间,其中$f$是$\Omega$中的一些非负可积函数。我们讨论了$0
