SOME CONVEX FAMILIES OF MULTIVALENTLY ANALYTIC FUNCTIONS DEFINED BY USING CERTAIN OPERATORS OF FRACTIONAL DERIVATIVES

Özet

Making use of fractional derivative operator, we introduce a general class of functions which are analytic and p-valent in the open unit disk U, and obtain a necessary and sufficient condition for a function to be in the class , distortion bounds, inclusion property and the radii of p-valently close-to-convexity, p-valently starlikeness, p-valently convexity for this generalized class of p-valent function.2000 Mathematics Subject Classification.
