On $p$-modulus estimates in Orlicz-Sobolev classes (1409.2167v2)

Abstract: Under a condition of the Calderon type on $\varphi$, we show that a homeomorphism $f$ of finite distortion in $W^{1,\varphi}_{\rm loc}$ and, in particular, $f\in W^{1,q}_{\rm loc}$ for $q>n-1$ in ${\Bbb R}^n$, $n\ge 3$, is a lower $Q$-homeomorphisms with respect to the $p$-modulus with $\left[ K_{I,\alpha}(x,f)\right]^{\beta}$, $p>n-1$ and a ring $Q_{}$-homeomorphism with respect to the $\frac{p}{p-n+1}$-modulus with $Q_{}(x)=K_{I,\alpha}(x,f)$ where $ K_{I,\alpha}(x,f)$ is its inner $\alpha$-dilatation and $\alpha=\frac{p}{p-n+1}$, $\beta=\frac{p-n+1}{n-1}$.
