The introduction of a subclass of close-to-convex functions using q-derivative operator shows new properties, indicating significant advances in mathematical analysis.
The objective of this paper is to introduce a new subclass of strongly close-to-convex functions defined with q-derivative operator and by subordinating to generalized Janowski function. We establish several useful properties such as coefficient estimates, distortion theorem, argument theorem, inclusion relations and radius of convexity for this class. Some relevant connections of the results investigated here with those derived earlier are mentioned.
