| Abstract: | In this paper, we introduced two new subclasses of the function class Σ of bi-univalent functions analytic in the open unit disc defined by convolution. Furthermore, we find estimates on the coefficients ∣a2∣ and ∣a3∣ for functions in these new subclasses. |
| Keywords: | Analytic and univalent functions Bi-univalent functions Starlike and convex functions Coefficients bounds |
