Univalent functions without common values
D. A. Kirillova Chair of Higher Mathematics, Far Eastern Academy for Humanities and Social Studies, Birobidzhan, Russia
Abstract:
In this paper we establish inequalities involving moduli of derivatives $|f_k'(0)|$ of functions $f_k$ univalent in the unit disk $|z|<1$ having no common values and translating zero in a point on the segment $[-1,1]$, $k=1,\dots,n$. We estimate $f_k$ by means of Schwarzian derivatives.
Keywords:
univalent functions, extremal partitions, conformal radius, Schwarzian derivative.
