Abstract

We introduce three new subclasses of Salagean-type analytic functions by using Janowski functions and q????dierence operator. We investigate inclusion theorem, sucient coecient estimates and distortion bounds for the functions belonging to these subclasses. Moreover, partial sums of these subclasses were obtained.
