An Application of the Briot-Bouquet Integral Operator for Differential Superordinations

Journal of Applied Computer Science & Mathematics, 2009
The notion of differential superordination wasintroduced as a dual concept of diffrential subordination bythe S. S. Miller and P. T. Mocanu. Using properties of theBriot-Bouquet linear operator, we obtain differentialsubordinations and superordinatios ...

Some properties of a class of holomorphic functions associated with tangent function

Demonstratio Mathematica
In this study, we define new class of holomorphic functions associated with tangent function. Furthermore, we examine the differential subordination implementation results related to Janowski and tangent functions. Also, we investigate some extreme point

New Criteria for Functions in a Class of Meromorphically Strongly Starlike Functions

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
The authors propose to investigate some new criteria for a certain class of meromorphically strongly starlike functions in the punctured open unit disk. Some intriguing applications that arise as special cases of the main results, which are presented in ...
