  • Abstract
    For analytic functions f(z) normalized by f(0) = f^ (0) − 1 = 0 in the open unit disk U, a class P(β1, β2; λ) of f(z) defined by some conditions with some complex numbers β1 and β2 is introduced. The object of the present paper is to consider some radius problems of 1/δf(δz) for f(z) ∈ S^∗_1(α).
