Abstract

‎In this paper‎, ‎by making use of q -derivative we introduce a new subclass of meromorphically univalent functions‎. ‎Precisely‎, ‎we give a necessary and sufficient coefficient condition for functions in this class‎. ‎Coefficient estimates‎, ‎extreme points‎, ‎convex linear combination Radii of starlikeness and convexity and finally partial sum property are investigated‎.
