摘要：
A new subclass of multivalent analytic functions is defined by means of q-difference operator and Janowski function. Some properties of functions in this new subclass such as sufficient and necessary conditions, coefficient estimates, growth and distortion theorems, radii of starlikeness and convexity , partial sums and closure theorems are studied.
