The Schwarz type Lemmas and the Landau type theorem of mappings satisfying Poisson's equations (1708.03924v2)
Published 13 Aug 2017 in math.CV
Abstract: For a given continuous function $g:~\Omega\rightarrow\mathbb{C}$, we establish some Schwarz type Lemmas for mappings $f$ in $\Omega$ satisfying the {\rm PDE}: $\Delta f=g$, where $\Omega$ is a subset of the complex plane $\mathbb{C}$. Then we apply these results to obtain a Landau type theorem, which is a partial answer to the open problem in \cite{CP}. %The obtained results are
