On univalent harmonic functions

2002
In Ann. Acad. Sci. Fenn., Ser. A I 9, 3--25 (1984; Zbl 0506.30007) \textit{J. Clunie} and \textit{T. Sheil-Small } introduced and studied the class \(S_H\) of complex valued, harmonic, orientation preserving, univalent functions \(f\) in the unit disk normalized by \(f(0)=0\), \(f'_z(0)-1=0\). Such functions have representation \[ f(z)=h(z)+\overline{g}

On Univalent Functions With Real Coefficients

The Annals of Mathematics, 1960
Mit Hilfe seines allgemeinen Koeffizientensatzes erhält der Verf. wichtige Ergebnisse über die Klasse \( S_{R} \) der im Einheitskreis \( E \) regulären und schlichten Funktionen \( f(z) \) mit der Normierung \( f(0)=0 \) und \( f^{\prime}(0)=1 \), deren Taylorsche Entwicklung um \( z=0 \) reelle Koeffizienten hat.
