A sharp stability inequality of Liouville's theorem for quasiregular mappings on bounded domains

Yi Ru-Ya Zhang

Let $n \geq 3$ and fix $p > n$ . We establish a sharp quantitative stability result in $W^{1, p}$ for Liouville's theorem for nonconstant, sense-preserving quasiregular mappings whose o…

Schoenflies solutions of conformal boundary values may fail to be Sobolev

Yi Ru-Ya Zhang

We show that there exists a planar Jordan domains $Ω$ with boundary of Hausdorff dimension $1$ such that, for any conformal maps $φ : D \to Ω$ , any homeomorphic extensi…
