Higher-Order Schippers-Schwarzian Derivatives for Non-Circular Starlike Functions

Pradip Das, Paweł Zaprawa, Nabadwip Sarkar

We find sharp upper bounds for the initial higher-order Schippers-Schwarzian derivatives $σ_{3} (f) (0)$ and $σ_{4} (f) (0)$ for several subclasses of univalent and starlike functions in t…

Sharp inequalities for Logarithmic Coefficients for Certain Classes of Univalent Functions

Sanju Mandal, Molla Basir Ahamed, Paweł Zaprawa

Let $S$ denote the class of functions $f (z) = z + \sum_{n = 2}^{\infty} a_{n} z^{n}$ that are analytic and univalent in the open unit disk $\mathbb{D} = \{z \in \mathbb{C} : |z…
