A study of sharp coefficient bounds for a new subfamily of starlike functions

Abstract In this article, by employing the hyperbolic tangent function tanhz, a subfamily S tanh ∗ $\mathcal{S}_{\tanh }^{\ast }$ of starlike functions in the open unit disk D ⊂ C $\mathbb{D}\subset \mathbb{C}$ : D = { z : z ∈ C  and  | z | < 1 } $$\begin{aligned} \mathbb{D}= \bigl\{ z:z\in \math...
