Subclass of analytic functions defined by a differential operator

摘要

In this paper, making use of a generalized differential operator, we introduce ecertain new subclasses of analytic functions various results including coefficient estimates, growth and distortion theorems, radii of starlikeness, convexity and close-to-convexity are obtained. In particular, we obtained integral means inequalities for the function f(z)∈T S_(αβ)~m(γ,k).
