The Bohr Phenomenon for Close-to-Convex Harmonic Mappings

Molla Basir Ahamed, Partha Pratim Roy

The classical Bohr inequality states that if $f (z) = \sum_{n = 0}^{\infty} a_{n} z^{n}$ is analytic and $∣ f (z) ∣ < 1$ in the unit disk $D$ , then $\sum_{n = 0}^{\infty} ∣ a_{n} ∣ r^{n} \leq 1$ …

Moduli difference of initial inverse logarithmic coefficients for starlike and convex functions

Molla Basir Aahmed, Partha Pratim Roy

Let $A$ denote the class of functions $f$ that are analytic in the open unit disk $D$ and satisfy the normalization conditions $f (0) = 0$ and $f^{'} (0) = 1$ . This p…
