On the Lipschitz continuity of certain quasiregular mappings between smooth Jordan domains. (English) Zbl 1379.30012

Authors’ abstract: We first investigate the Lipschitz continuity of \((K,K^\prime)\)-quasiregular \(C^{2}\) mappings between two Jordan domains with smooth boundaries, satisfying certain partial differential inequalities concerning Laplacian. Then two applications of the obtained result are given: As a direct consequence, we get the Lipschitz continuity of \(\rho\)-harmonic \((K,K^\prime)\)-quasiregular mappings, and as the other application, we study the Lipschitz continuity of \((K,K^\prime)\)- quasiconformal self-mappings of the unit disk, which are the solutions of the Poisson equation \(\Delta w = g\). These results generalize and extend several recently obtained results by Kalaj, Mateljević and Pavlović.
