Space Quasiconformal Mappings and Neumann Eigenvalues in Fractal Domains

Autor: Gol'dshtein, V., Hurri-Syrjänen, R., Ukhlov, A.

We study the variation of the Neumann eigenvalues of the $p$-Laplace operator under quasiconformal perturbations of space domains. This study allows to obtain lower estimates of the Neumann eigenvalues in fractal type domains. The suggested approach

We consider integral inequalities in the sense of Choquet with respect to the Hausdorff content $\mathcal{H}_\infty^δ$. In particular, if $Ω$ is a bounded John domain in $\mathbb{R}^n$, $n\geq 2$, and $0 δ/n$.
