Abstract:

 

Let S∗(qc)S∗(qc)\mathcal{S}^*(q_c) denote the class of functions fff analytic in the open unit disc ΔΔ\Delta, normalized by the condition f(0)=0=f′(0)−1f(0)=0=f′(0)−1f(0)=0=f'(0)-1 and satisfying the following inequality  $\left|\left(\frac{zf'(z)}{f(z)}\right)^2-1\right| < c \quad     (z\in\Delta, 0
                                    .
