Properties on a subclass of analytic functions defined by a fractional integral operator.

In this paper we have introduced and studied the subclass L(λ, d, α, β) using the fractional integral as- sociated with the convolution product of Sălăgean operator and Ruscheweyh derivative. The main object is to investigate several properties such as coefficient estimates, distortion theorems, closure theorems, neigh- borhoods and the radii of starlikeness, convexity and close-to-convexity of functions belonging to the class L(λ, d, α, β).
