Abstract

Let f(z) = z + a~2~z^2^ + … be an analytic function in the unit disk 𝒰 = {z : |z| < 1}. Such a function belongs to the class G~b~ defined by Silverman if the quotient of the analytic representations of convexity and starlikeness of the function maps the unit disk into a disk with center 1 and radius b. By using the Jack lemma we analyze the relation between the class G~b~ and the class S*[A,B] and its subclasses.
