Abstract

In this paper, we introduce a new subclass of analytic and bi-univalent functions by using generalized Salagean $q$-differential operator in open unit disc $E=\left \{ z:z\in \mathbb{C} \text{ and }\left \vert z\right \vert <1\right \} $. By using Faber polynomial expansions and $q-$analysis to find a general coefficient bounds $|a_{n}|,$ for $n\geq 3,$ of class of bi-subordinate functions, also find initial coefficients bounds$.$ We also highlight some known consequences of our main results.

Keywords
