%0 Journal Article %T Initial Bounds for Certain Classes of Bi-Univalent Functions Defined by Horadam Polynomials %A Abirami %A Chinnaswamy %A Magesh %A Nanjundan %A Yamini %A Jagadeesan %J - %D 2020 %R https://doi.org/10.1155/2020/7391058 %X The main purpose of this article is to make use of the Horadam polynomials and the generating function , in order to introduce three new subclasses of the bi-univalent function class For functions belonging to the defined classes, we then derive coefficient inequalities and the Fekete¨CSzeg£¿ inequalities. Some interesting observations of the results presented here are also discussed. We also provide relevant connections of our results with those considered in earlier investigations %U https://www.hindawi.com/journals/aaa/2020/7391058/
