An Application of Jackson's -Derivative to a Subclass of Starlike Functions with Negative Coefficients
Feras Yousef, Amal Al-Shible, Sibel Yalçın
In this paper, we introduce and investigate the subclass of starlike functions with negative coefficients by using the differential operator $Υ_{τ,p…
A Comprehensive Subclass of Bi-Univalent Functions Associated with Chebyshev Polynomials of the Second Kind
Feras Yousef, Somaia Alroud, Mohamed Illafe
Our objective in this paper is to introduce and investigate a newly-constructed subclass of normalized analytic and bi-univalent functions by means of the Chebyshev polynomials of…
New Subclasses of Analytic and Bi-Univalent Functions Endowed with Coefficient Estimate Problems
Feras Yousef, Somaia Alroud, Mohamed Illafe
Inspired by the recent works of Srivastava et al. (2010), Frasin and Aouf (2011), and Caglar et al. (2013), we introduce and investigate in the present paper two new general subcla…
Fekete-Szego Inequality for Analytic and Bi-univalent Functions Subordinate to Chebyshev Polynomials
Feras Yousef, B. A. Frasin, Tariq Al-Hawary
In the present paper, a new subclass of analytic and bi-univalent functions by means of Chebyshev polynomials is introduced. Certain coefficient bounds for functions belong to this…
