Some estimation about Tayler-Maclaurin coefficients of generalized subclasses of bi-univalent functions
S. A. Saleh, Alaa H. El-Qadeem, Mohamed A. Mamon
Our objective in this paper is to introduce and investigate comprehensive-constructed subclasses of normalized analytic and bi-univalent functions on the unit open disc. Bounds for…
Upper bound of second Hankel determinant of subclass of bi-univalent functions defined by subordination
Alaa H. El-Qadeem, Mohamed A. Mamon
In this paper, new class of bi-univalent functions are introduced. Upper bound of the second Hankel determinant of subclass of bi-univalant functions class , which de…
Some Aspect of Certain two Subclass of Analytic Functions with Negative Coefficients Defined by Rafid Operator
Alaa H. El-Qadeem, Sameerah K. Al-ghazal
In this paper, we define the subclasses and of analytic functions in the open unit disc of complex plain. Then the neighborhood propertie…
On a Subclass of p-Valent Functions with Negative Coefficients Defined by Using Rafid Operator
A. H. El-Qadeem, S. K. Al-ghazal
By using Rafid operator we define the subclass and of analytic and p-valent functions with negative coefficients we investigate some sharp re…
