Abstract

Abstract In this paper, we introduce and investigate some new subclasses S γ n , q ( λ , m , ϕ ) and W x k , α ( λ , δ , ϕ ) of bi-univalent functions in the unit disk U, which satisfies the qusi-subordination condition. We obtain estimates the first two Taylor-Maclarurin coefficients |a 2| and |a 3|.
