ON functors Dd(-)and Dd(M-)

Let be a Noetherian ring and be a non-negative integer . Let be an -module . We define the - transform functors and on the category of -modules . We show that , if is an injective - module , then is injective - module . Also, a criterion under which the isomorphism holds will be investigated . yllaiiF , we investigate , where and are -modules .
