Abstract
Using the Wright's generalized hypergeometric function, we investigate a class W(q, s; A, B, λ) of analytic functions with negative coefficients. We derive many results for the modified Hadamard product of functions belonging to the class W(q, s; A, B, λ). Moreover, we generalize some of the distortion theorems to the classical fractional integrals and derivatives and the Saigo (hypergeometric) operators of fractional calculus.
Key words and phrases.: Wright's generalized hypergeometric function; modified Hadamard product; fractional calculus
