On generalized fractional integral operator involving Fox's H-function and its applications to unified subclass of prestarlike functions with negative coefficients

The aim of present paper is to find out different interesting properties and characterization of unified class P-gamma (A, B, alpha, sigma) of prestarlike functions with negative coefficients in the unit disc U. Furthermore, distortion theorems involving a generalized fractional integral operator involving well-known Fox's H-function for functions in this class are proved.
