摘要：

In this paper, we obtain the coefficient bounds and closure properties for a class of analytic functions defined using q-differential operator which are closely related to the classes of alpha-spiralike and convex alpha-spiral functions. Also we investigate convolution properties and necessary and sufficient conditions for functions in the defined class.
