In this paper we introduce new subclass HP (α, β, λ) of star like functions in the open unit disk defined by using certain fractional derivative operator. We obtain coefficient estimates and distortion theorems for functions belonging to the above subclass. Also results include distortion theorems (involving the generalized fractional derivative operator) are considered. Further results giving extreme points, modified Hadamard product, inclusion properties, and the radii of close-to-convexity. Star likeness and convexity for fractions belonging to this subclass are also discussed. |
