On starlikeness and close-to-convexity of certain analytic functions

Sufficient Conditions for a New Class of Polynomial Analytic Functions of Reciprocal Order alpha

In this paper, we consider a new class of analytic functions in the unit disk using polynomials of order alpha. We give some sufficient conditions for functions belonging to this class.

On Sandwich theorems for certain classes of analytic functions

The purpose of this present paper is to derive some subordination and superordination results for certain analytic functions in the open unit disk. Relevant connections of the results, which are presented in the paper, with various known results are also considered.

Close-to-convexity and Starlikeness of Certain Analytic Functions Defined by a Linear Operator (communicated by Indrajit Lahiri)

The main object of the present paper is to derive some results for multivalent analytic functions defined by a linear operators. As a special case of these results, we obtain several sufficient conditions for close-to-convexity and starlikeness of certain analytic functions.
