inclusion and argument properties for a certain class of analytic functions based on fractional derivatives

In this work, we introduce and investigate an interesting operator q ν λ based on fractional derivative which is introduced by owa and srivastava in [10]. we consider a new technique to prove our results and then, we introduce two subclasses of analytic functions in the open unit disk u concerning with this operator. some results such as inclusion relations, subordination properties, integral preserving properties and argument estimate are investigated.
