Fekete-Szegö inequality for analytic and Bi-univalent functions subordinate to Cebyshev polynomials


Feras Yousef, B A Frasin, Tariq Al-Hawary




In the present study, a new subclass of analytic and bi-univalent functions by means of Chebyshev polynomials is introduced. Certain coefficient bounds for functions belong to this subclass are obtained. Furthermore, the Fekete-Szegö problem in this subclass is solved
