@ARTICLE{Hameed Mohammed, author = {Hameed Mohammed, Nafya and }, title = {Coefficient Bounds for a New Class of Bi-Univalent Functions Associated with Subordination}, volume = {2}, number = {2}, abstract ={The main purpose of this article is to introduce and investigate the subcategory $mathcal{H}_{Sigma}(n,beta;phi)$ of bi-univalent functions in the open unit disk $mathbb{U}$ related to subordination. Moreover, estimates on coefficient $|a_n|$ for functions belong to this subcategory are given applying different technique. In addition, smaller upper bound and more accurate estimation than the previous outcomes are obtained. }, URL = {http://maco.lu.ac.ir/article-1-89-en.html}, eprint = {http://maco.lu.ac.ir/article-1-89-en.pdf}, journal = {Mathematical Analysis and Convex Optimization}, doi = {10.52547/maco.2.2.8}, year = {2021} }
