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…

The Fekete--Szegö problem and filtration of generators

Mark Elin, Fiana Jacobzon, Nikola Tuneski

In this paper we study an interpolation problem involving the Fekete--Szegö functional. It turns out that this problem links to the so-called filtration of infinitesimal generators…

Coefficients of the inverse of functions for the subclass of $U (λ)$

Milutin Obradović, Nikola Tuneski

Let $A$ be the class of functions $f$ that are analytic in the unit disk $D$ and normalized such that $f (z) = z + a_{2} z^{2} + a_{3} z^{3} + \dots$ . Let $0 < λ \leq 1$ and \[ {\mat…

Sharp bounds of Hankel determinants of second and third order for inverse functions of certain class of univalent functions

Milutin Obradović, Nikola Tuneski

Let $A$ be the class of functions that are analytic in the unit disc $D$ , normalized such that $f (z) = z + \sum_{n = 2}^{\infty} a_{n} z^{n}$ , and let class ${\mathcal U}(λ…
