Classes with negative coefficients and starlike with respect to other points II
A class Ss*T(α, β, σ, k) of functions f which are analytic and univalent in the open unit disk D = {z : |z| < 1} given by f(z) = z - Σn=2∞anz n and satisfying the condition |zf′(z)/f(z)-f(-z) - k| < β|αzf′(z)/f(z) - f(-z) - (2σ - k) for 0 ≤ α ≤ 1, 0 < β ≤ 1, 0 ≤ σ â‰...

| الملخص: | A class Ss*T(α, β, σ, k) of functions f which are analytic and univalent in the open unit disk D = {z : |z| < 1} given by f(z) = z - Σn=2∞anz n and satisfying the condition |zf′(z)/f(z)-f(-z) - k| < β|αzf′(z)/f(z) - f(-z) - (2σ - k) for 0 ≤ α ≤ 1, 0 < β ≤ 1, 0 ≤ σ ≤1/2 < k ≤ 1, z ∈ D, is introduced and studied. An analogous class Sc*T(α, β, σ, k) and Ssc*T(α, β, σ, k) are also examined |
