AB - <p style="text-align: justify;">In this paper, we introduce several new subclasses of the function class
$\it\Sigma$ of bi-univalent functions analytic in the open unit disc defined by convolution.
Furthermore, we investigate the bounds of the coefficients $|a_2|$ and $|a_3|$ for functions
in these new subclasses. The results presented in this paper improve or generalize
the recent works of other authors.</p>
