| چکیده | ||
| In this paper, we introduce a subclass of close-to-convex functions defined in terms of generalized Ruscheweyh derivative operator. We determine coefficient bounds for functions of complex order $b$ analytic in the open unit disk $\Delta =\left\{ z\in \mathbb{C} :\left\vert z\right\vert <1\right\} $. | ||
