Subclasses of analytic functions defined by a generalized differential operator. (English) Zbl 1195.30031
Summary: Making use of a generalized differential operator, we introduce certain new subclasses of analytic functions. Various results including coefficient estimates, growth and distortion theorems, radii of starlikeness, convexity and close-to-convexity are obtained.
