The Booth Lemniscate Starlikeness Radius for Janowski Starlike Functions
Somya Malik, Rosihan M Ali, V. Ravichandran
The function , \, , maps the open unit disc onto the interior of a domain known as the Booth lemniscate. Associated with this function…
Starlikeness of Analytic Functions with Subordinate Ratios
Rosihan M. Ali, Kanika Sharma, V. Ravichandran
Let be a non-vanishing analytic function in the open unit disc with . Consider the class consisting of normalized analytic functions whose ratios , $g(z)…
Bohr operator on analytic functions
Yusuf Abu-Muhanna, Rosihan M. Ali, See Keong Lee
For and a fixed in the unit disk, the Bohr operator 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 be the class of analytic functions in the unit disk $\ID$ with the normalization , and satisfying the condition $$\left |z^2\left (\frac{z}{f(z)}…
The spherical metric and univalent harmonic mappings
Yusuf Abu Muhanna, Rosihan M. Ali, Saminathan Ponnusamy
Let be a harmonic univalent map in the unit disk , where and are analytic. We obtain an improved estimate for the second coefficient of .…
Characterizing Rotationally Typically Real Logharmonic Mappings
Najla M. Alarifi, Zayid Abdulhadi, Rosihan M. Ali
This paper treats the class of normalized logharmonic mappings f(z) = zh(z)bar{g(z)} in the unit disk satisfying ϕ(z) = zh(z)g(z) is analytically typically real. Every such mapping…
