Title: Hankel Determinant for starlike and convex functions.
Abstract:Denote S to be the class of functions which are analytic, normalised and univalent in the open unit disc D = {z : |z| < 1}. The important subclasses of S are the class of starlike and convex functions...Denote S to be the class of functions which are analytic, normalised and univalent in the open unit disc D = {z : |z| < 1}. The important subclasses of S are the class of starlike and convex functions, which we denote by S and C. This paper focuses on attaining sharp upper bounds for the functional |a2a4−a3| for functions f(z) = z + ∑∞ n=2anz n belonging to S and C. Mathematics Subject Classification: Primary 30C45Read More
