• ON SUFFICIENT CONDITIONS FOR CERTAIN SUBCLASSES OF ANALYTIC AND UNIVALENT FUNCTIONS
Abstract
The aim of the present paper is to obtain sufficient conditions for starlike functions of order . We establish two theorems. The first theorem provides improvement of the sufficient conditions for starlikeness obtained earlier by several research workers such as Lewandowski et al. [5], Li and Owa [6], Nunokawa et al. [8,9], Ramesha et al. [10] and Ravichandran et al. [11]. The second theorem gives sufficient conditions for a function to be in the subclass of analytic and univalent functions on the unit disk.
