Abstract:
In this paper, we investigate two new subclasses $S^*_sigma(a, b)$ and $nu_sigma(a, b)$ of $sigma$ consisting of analytic and bi-univalent functions satisfying subordinations in the open unit disk $mathbb{U}$. We consider the Fekete-Szeg"{o} inequalities for these new subclasses. Also, we establish estimates for the coefficient for these subclasses.
