Abstract :
The main purpose of this article is to introduce and investigate the subcategory HƩ(n; β; ϕ) of bi-univalent functions in the open unit disk U related to subordination. Moreover, estimates on coefficient janj for functions belong to this subcategory are given applying different a technique. In addition, smaller upper bound and more accurate estimation than the previous outcomes are obtained.
