© Tübitak. Let (β n )n≥2 be a sequence of nonnegative real numbers and δ be a positive real number. We introduce the subclass A(β n , δ) of analytic functions, with the property that the Taylor coefficients of the function f satisfies ∑ n≥2δ β n |a n | ≤ δ, where f(z) = z + ∑ n=2δ a n z n . The cla...
