On a Subclass of Starlike Functions Associated with a Strip Domain

S. Sivaprasad Kumar, Neha Verma

In the present investigation, we introduce a new subclass of starlike functions defined by ${\mathcal{S}}_{\tau }^{\ast }:=\{f\in \mathcal{A}:z{f}^{\prime }(z)/f(z)\prec 1+\arctan z=:\tau (z)\}$, where $τ(z…
