Starlikeness criteria for a certain class of analytic functions

Abstract: We denote by , the class of all analytic functions in the unit disc with the normalization . For a positive number , we denote by the class of all , such that , and satisfying the condition A function is said to be in if . In this paper, we find conditions on , and such that is included in the class of all starlike functions of order , or the class of all strongly starlike functions of order , or , respectively.
