On The Upper Bound Estimates for the Coefficients of Certain Class Bi-Univalent Functions of Complex Order

Autor: Ruslans Aleksejevs, Jekaterina V. Aleksejeva, Sharif E. Guseynov

Publikováno v: Academic Journal of Applied Mathematical Sciences. :101-113

In this paper, we introduce and investigate a subclass of analytic and bi-univalent functions of complex order in the unit disk in complex plane. We obtain upper bound estimates for the initial three coefficients of the functions belonging to this cl
