The first main case is the behavior of Möbius transformations of the unit ball in $\mathsf{R}^n$ onto itself. In the second main case we study the polynomials of the unit disk onto a subdomain of the complex plane. In both cases sharp Lipschitz constants are obtained. }, number={1}, journal={MATHEMATICA SCANDINAVICA}, author={Simić, Slavko and Vuorinen, Matti and Wang, Gendi}, year={2015}, month={Mar.}, pages={86–103} }
