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. Keywords: Wright's generalized hypergeometric function, modified Hadamard product, fractional calculus. MSC: 30C45, 26A33 [ Fulltext-pdf (169 KB)] for subscribers only. |
