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

Qing-Hua Xu, Guang-Ping Wu

Abstract

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