About a generalized class of close-to-convex functions defined by q-difference operator
In this paper we generalize the class of close-to-convex functions by the q-difference operator, for functions with negative coefficients and we study some properties of this generalized class. An analogue of the Pólya-Schoenberg conjecture is proved.
