Abstract
The theory of q-analysis has many applications in various sub- elds of math- ematics and quantum physics. In the present article, we de ne the class Tn( ; ; q) using the S al agean q-di erential operator. For functions belonging to this class we obtain co- e cient estimates, extreme points and integral preserving properties .
Keywords
