Sharp bounds of logarithmic coefficients for a class of univalent functions

Milutin Obradović, Nikola Tuneski

Let $U (α, λ)$ , $0 < α < 1$ , $0 < λ < 1$ be the class of functions $f (z) = z + a_{2} z^{2} + a_{3} z^{3} + \dots$ satisfying $(\frac{z}{f ( z )})^{1 + α} f^{'} (z) - 1 < λ$ i…

Certain properties of the class of univalent functions with real coefficients

Milutin Obradović, Nikola Tuneski

Let $U^{+}$ be the class of analytic functions $f$ such that $\frac{z}{f ( z )}$ has real and positive coefficients and $f^{- 1}$ be its inverse. In this paper we give sharp e…
