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|…

On classes of meromorphic locally univalent functions defined by differential inequalities

See Keong Lee, Saminathan Ponnusamy, Karl-Joachim Wirths

n this article we consider functions meromorphic in the unit disk. We give an elementary proof for a condition that is sufficient for the univalence of such functions which also co…
