Abstract

In the present work, using suboridination techniques, we study certain subclasses of analytic univalent functions of complex order  associated with the sine function. The sharp coefficient bounds and the sharp Fekete-Szegö inequality are obtained for these subclasses. Additionally, a sharp radius result is also derived for a certain subclass of Janowski starlike functions. These results generalize several known results as special cases and contribute to the broader theory of univalent functions.
