Coefficient Estimate for a Subclass of Univalent Functions with Respect to Symmetric Points

Abstract

In this paper, the subclasses ${\mathcal{S}}_s^{\ast }(g)$ and
${\mathcal{K}}_s^{\ast }(g)$ of analytic functions are introduced. we obtain coefficient bounds for $f(z)$ when $f(z)$ is in the class ${\mathcal{S}}_s^{\ast }(g)$ or is in the class ${\mathcal{K}}_s^{\ast }(g)$. These results generalize many known results.
