On the difference of coefficients of univalent functions

Milutin Obradovic, Derek K. Thomas, Nikola Tuneski

For $f \in S$ , the class of normalized functions, analytic and univalent in the unit disk $D$ and given by $f (z) = z + \sum_{n = 2}^{\infty} a_{n} z^{n}$ for $z\in \mathbb{…

Toeplitz determinants whose elements are the coefficients of univalent functions

Md Firoz Ali, D. K. Thomas, A. Vasudevarao

Let $S$ denote the class of analytic and univalent functions in $D := {z \in C : ∣ z ∣ < 1}$ of the form $f (z) = z + \sum_{n = 2}^{\infty} a_{n} z^{n}$ . In this paper,…

Successive coefficients of convex functions

Derek Thomas

It is shown that for $f$ analytic and convex in $z \in D = {z : ∣ z ∣ < 1}$ and given by $f (z) = z + \sum_{n = 2}^{\infty} a_{n} z^{n}$ , the difference of coefficients $||a_{3}|-|a_{2}||\le 25/48…
