Certain Integral Operator and Strongly Starlike Functions

Sufficient Conditions for Certain Types of Functions to Be Parabolic Starlike

In this paper sufficient conditions are determined for functions of the form f(z) = z 1 + ∞ ∑ 1 bkz k , f(z) = z (1 + zn)k and certain other types of functions to be parabolic

Certain sufficient conditions for strongly starlike functions associated with an integral operator

By using the method of differential subordinations, we derive certain sufficient conditions for strongly starlike functions associated with an integral operator. All these results presented here are sharp. 2000 Mathematics Subject Classification. Primary 30C45; Secondary 30A10.

On sufficient condition to be in a certain subclass of starlike functions defined by subordination

An interesting criterion was given by Tuneski [N. Tuneski, On the quotient of the representations of convexity and starlikeness, Math. Nachr. 248–249 (2003) 200–203] for the analytic functions to be in the class S 1⁄21þAz 1þBz and its subclasses, where 1 6 B < A 6 1. This result is an extension of an earlier result of Silverman [H. Silverman, Convex and starlike criteria, Int. Math. Math. Sci. ...

On Certain Classes of Meromorphically Starlike Functions

The object of the present paper is to introduce a new class E,(a) of meromorphic functions defined by a multiplier transformation and to investigate some properties for the class Further we study integrals offunctions in
