Bohr operator on analytic functions

Yusuf Abu-Muhanna, Rosihan M. Ali, See Keong Lee

For $f (z) = \sum_{n = 0}^{\infty} a_{n} z^{n}$ and a fixed $z$ in the unit disk, $∣ z ∣ = r,$ the Bohr operator $M_{r}$ is given by \[\mathcal{M}_r (f) = \sum_{n=0}^{\infty} |a_n|…

Differential Inequalities and Univalent Functions

Rosihan M. Ali, Milutin Obradović, Saminathan Ponnusamy

Let $M$ be the class of analytic functions in the unit disk $\ID$ with the normalization $f (0) = f^{'} (0) - 1 = 0$ , and satisfying the condition $$\left |z^2\left (\frac{z}{f(z)}…
