Abstract

In this paper we have introduced and studied the subclass \mathcal{D}_{m,n}(\delta ,\lambda ,d,\gamma ,\beta ) using the fractional integral operator associated with a linear differential operator. The main object is to investigate several properties such as coefficient estimates, distortion theorems, closure theorems, neighborhoods and the radii of starlikeness, convexity and close-to-convexity of functions belonging to the class  \mathcal{D}_{m,n}(\delta ,\lambda ,d,\gamma ,\beta ).

Keywords: Analytic functions, Univalent functions, Radii of starlikeness and convexity, Neighborhood property
