Distortion of quasiregular mappings and equivalent norms on Lipschitz-type space
Last modified: 2014-04-12
Abstract
We prove a quasiconformal analogue of Koebe's theorem related to the average Jacobian and use a normal family argument here to prove a quasiregular analogue of this result in certain domains in $n$-dimensional space.
As an application, we establish that Lipschitz-type properties are inherited by a quasiregular function from its modulu. We also prove some results of Hardy- Littlewood type for Lipschitz-type spaces in several dimensions, give the characterization of Lipschitz-type spaces for quasiquasiregular mappings by the average Jacobian and give a short review of the subject. In particular, we solve so called Dyakonov's problem.
