On Certain Subclasses of Analytic Functions Defined by Differential Subordination

Certain Subclasses of Analytic Functions with Complex Order

Two new subclasses of analytic functions of complex order are introduced. Apart from establishing coefficient bounds for these classes, we establish inclusion relationships involving (n-δ) neighborhoods of analytic functions with negative coefficients belonging to these subclasses.

Subordination Properties for New Certain Subclasses of Univalent Functions

In this paper, we obtain some subordination results for certian subclasses of univalent functions defined by convolution.

Subordination Properties for Certain Subclasses of Prestarlike Functions

Making use of generalized Sǎlǎgean derivative operator in this paper, we define a unified class of starlike functions with negative coefficients and obtain subordination results, partial sums, integral transforms for this class. Further integral means and square root transformation results are discussed. AMS (MOS) Subject Classification Codes: 30C45
