Abstract :
Let R be a Noetherian ring and d be a non-negative integer. Let M be an R-module. We define the d- transform functors D_d (-) and D_d (M,-) on the category of R-modules. We show that, if M is an injective R- module, then L_d (M) is injective R- module. Also, a criterion under which the isomorphism M ? D_d (M) holds will be investigated. Finally, we investigate D_d (M,N), where M and N are R-modules.
