On P-Valently Close-To-Convex, Starlike and Convex Functions

Year 2012, Volume: 41 Issue: 5, 635 - 642, 01.05.2012

Abstract

The main object of the present paper is to derive several sufficient conditions for close-to-convexity, starlikeness, and convexity of certain p-valent analytic functions in the unit disk. Some interesting consequences of the main results are also mentioned.
