ON ALPHA-CLOSE-TO-CONVEX FUNCTIONS OF ORDER BETA
摘要
Let M_β(α) [α≥ 0 and β≥ 0] denote the class of all functions f(z) =z + ^∞Σ_(n = 2) a_n z^n analytic in the unit disc U with f'(z)f(z)/z≠ 0 and which satisfy for z=re^(iθ) εU the condition (The equation is abbreviated) for all θ2 ＞ θ1. In this note we show that each fεM_β(α) is close-to-star of order m when o ＜β≤α.
