Some applications of differential subordination for certain starlike functions

We consider the class ${\mathcal{S}}^{\ast }(q_c)$ of normalized starlike functions $f$ analytic in the open unit disk $\mathrm{\mid }z\mathrm{\mid }<1$ that satisfying the inequality \begin{equation*} \left|\left(\frac{zf’(z)}{f(z)}\right)^2-1\right|<c \quad (0<c\leq1). \end{equation*} In this article, we present some subordination relations and these relations are then used to obtain some corollaries for some subclass of analytic functions.
