A short proof of the self-improving regularity of quasiregular mappings.
Xiao Zhong and Daniel Faraco
Abstract
We provide a short proof of a theorem, due to Iwaniec & Martin and Iwaniec, on the self improving integrability of quasiregular mappings. The proof relies on Lipschitz approximations of Sobolev functions.
