Subordination, Bounded Functions, Univalent Functions, Starlike Functions, Convex Functions and Close-to-convex Functions.


We introduce some subclasses of close-to-convex functions and obtain sharp results for coefficients, distortion theorems and argument theorems from which results of several authors follows as special cases.
